    hello this is 10 Kalinin I walk for a
    unerotic Community College and I'm going
    to be your solder works instructor this
    semester and I've been teaching
    SolidWorks for about five years now and
    the one thing that has been requested an
    awful lot our videos typically a my goal
    a bit fast in class and I have an accent
    and it can be hard to understand
    sometimes so a lot of students have
    asked me Tim do you mind making some
    videos and the more videos I make and
    they seem to seem to really help so this
    is a this is going to be SolidWorks
    lesson number one it's going to go over
    everything that I've covered in the
    first class note that these videos are
    supplemental so it's it's you know you
    know you can't can't be cut you can't
    miss class and then just watch the video
    this is just going over a lot of the
    stuff that I'm going to cover in class
    ok I'm sorry about this let me just get
    rid of that sorry about that and
    hopefully this thing is recording still
    anyway so the first thing I want to show
    you is how to Lottie you're going to go
    home and you're going to want to install
    solar works in your whole computer and
    you know from the feedback that I get
    from students it's it can be a little
    bit of a pain to install and it's going
    to take a little bit of time but I'm
    going to show you a few of the steps
    that you need to do actually install
    SolidWorks the first thing you need to
    know is whether you have a 32-bit
    machine or a 64-bit machine now how do
    you find that out
    you can find that out now you need to
    I'm using Windows 7 here but you need to
    somehow find if you right click on my
    computer it might be up there or here
    you can go to properties okay
    now I'm not showing you my computer
    because I have some IP address stuff
    that I don't want the words and all via
    YouTube but anyway go to my go to
    computer go to properties and that will
    tell you whether you have a 32-bit or
    whether you will have a 64-bit and that
    that's important I have a 64-bit machine
    so I installed the 64-bit and
    saw works now I'm also using 2013 you're
    going to probably use in 2014 I want you
    to use them of up today's edition or
    opportunit for ISM that you can get no
    what are you going to do forced you
    don't need to pay for SolidWorks because
    your student is AACC you can download it
    for free and we have a 364 day license
    for you and if you're on another college
    you need to obtain something called an
    sdk ID from your instructor so what are
    you going to do you're going to go to
    google you're going to type in
    SolidWorks education download so type
    that in in google or an internet browser
    or something and the first link should

    Watch video from 03:00 - 6:00

    be the student access form let's click
    on that now open my address here have
    SolidWorks comm /sw forward slash
    education forward slash SDL underscore
    form dot HTML if you don't have that up
    there you're in the wrong side so you
    need to figure that out or you can type
    it up there if you want that what if you
    type this in where will it bring it
    it'll bring it to the student access
    form sourc student License Program
    download version you have to fill out
    all the information are you and
    educators your student stick in your
    name Joe Bloggs school name and oral to
    fill all this incorrectly Community
    College school type two year of college
    major
    let's have a look it doesn't really
    matter mechanical multiplied you Asian
    you know it's twelve months from now so
    orders are going to be it's only August
    2015
    city Arnold Maryland's postal code to
    101 to come to USA version 2014 to 2015
    get the most up-to-date
    origen var name you don't need to worry
    about that email address stick in the
    proper email stick in an email that you
    can access because they're going to
    email you a cord or something but you're
    gonna have to put in make sure you put
    in the correct email now school license
    ID sdk ID you're going to put in a
    number here ain't going to give you that
    number okay I'm going to write it down
    on on I'm going to write it down on your
    first day of class don't share it with
    anyone else on the internet we have 50
    people that we can give this out to a
    year so it's limited so keep it yourself
    it's gets your SDK iud don't give it to
    anyone else I'm going to give you this
    number so don't worry about it you'll
    have that number before you install this
    at home
    put in the right email address click on
    a request download so what you're going
    to do is hopefully you have a good
    internet connection at home because it
    takes about 1 gigabyte of data so it's
    going to take about a go to at least
    half an hour to do this and if you don't
    have the internet at home you could do
    do this in the college don't thing you
    could do is you can bring your laptop in
    to the college and download this at the
    college well it's going to take a little
    bit of time once you download the entire
    file then you're going to install it
    once you're installing it it's going to
    ask for some sort of number it's going
    to ask for some sort of codes where
    where is that code it's going to be in
    your email address that you provided and
    then you should hopefully install it I
    have a feeling it's going to take about
    2 to 3 hours to install it SolidWorks
    and it's water in order for me to

    Watch video from 06:00 - 9:00

    purchase SolidWorks to do some
    commercial work with that it could cost
    me four or five thousand dollars this is
    you're getting a you're getting a design
    package for a year put a little bit of
    grief it's going to take about two to
    three hours to install so hopefully at
    this stage you have SolidWorks installed
    at home or you're going to use one of
    the computer solar works in the labs so
    what are we going to do for this first
    what are we going to do for this first
    lesson I'm going to give you this PDF
    and it's called SolidWorks lesson one
    sizes and all we're going to do is for
    the first couple of weeks we're going to
    just do 2d sketches like shown we're
    going to we're not going to worry about
    creating funky 3d models we're just
    going to spend a good two weeks just
    working on sketches just 2d sketches
    like you see here so what we'll do is
    we're just going to run through each
    sketch and you'll see that the sketch is
    starting to get more and more
    complicated and they start to begin to
    get cleaner heading pretty quickly so
    we're going to work on this first sketch
    that's that you know I'd rather I'd
    rather teacher by doing instead of
    lecturing for ages and ages so you're
    going to click on SolidWorks
    hopefully there's an icon on your screen
    if there's enough you're going to find
    it here like so and and this will open
    up so this is the main this is this is
    the main solar works what are we going
    to do we're going to click on file new
    and hopefully this new saw works
    document will open up you have a choice
    between a part and assembly or a drawing
    okay we're going to spend about two to
    three months just working on parts okay
    so what you want to do click on part and
    go okay okay and this will open up now
    um let's this is the main ribbon
    they call this a ribbon here these are
    hubs now you're going to spend the
    majority of your time about 90% of your
    time or even 95 just going between
    features and sketch like you know very
    very rarely do I go into these order
    tree here features and sketches all you
    need so just go back and forth this
    section here is called
    the feature tree now we'll get into that
    later you have some icons here and your
    other important icons here that we use
    an awful lot so what do we do the first
    thing you're going to do is you're going
    to click on sketch you're going to make
    sure you're in the sketch tab and you're
    going to create we want to create a new
    sketch so let's do that and what does it
    do it says if you want to create a
    sketch you're going to have to either
    pick select a plane
    almost to create a sketch for the entity
    what happens with what happens with
    SolidWorks is whenever it has any sort
    of dialogue or once it needs more
    information it takes this area of the
    feature tree and it goes here here's

    Watch video from 09:00 - 12:00

    your message so it can't it's waiting
    for you to do something here now what
    you're going to do whenever you create a
    new sketch you're going to click on the
    front plan just just accept that for a
    while okay click on the font plan
    I know look what we have Y and we have X
    and now we're in a 2d space okay so
    let's let's just let me press X and go
    don't save let's do it again I click on
    new forget that new part I click on
    sketch and then I click on font plan all
    right this is you can see my ye and my X
    you can see that it's this front there
    and you can see here what's going on
    you're just the origin now notice I want
    you to look here for a second here okay
    notice this the approximate or the value
    that my pointer there is roughly around
    three and a half inches in the X and
    it's zero and the y if I move it up
    there it's three and a half inches in
    the X and three and a half inches in the
    Y if I move a close to the origin we get
    zero zero zero okay so let's go back and
    have a look what do we want to draw we
    want to draw this t-shaped it looks like
    a jackhammer
    alright and I'm being I'm being lazy in
    a mock unit/units but all of these units
    for the time being are in millimeters
    okay so everything you see here are
    millimeters now what's a quick way of
    changing so down here I'm just going to
    highlight here it's saying that the
    units are inch pound second American
    inches of American units we like that
    but what we're going to do is we're just
    going to switch this to be millimeters
    like so okay so there's a quick way of
    changing it
    but the only issue is is whatever you
    change the units it makes you redo a
    sketch so let's just redo it again
    sketch which plan do you want we want it
    on the front plan or feeling confused it
    too much there no I'm going to just for
    fun I'm going to click on a line and I'm
    just going to create some lines like so
    all I'm doing here is I'm left I'm using
    my left mouse button and just notice how
    it snaps to the 90 degrees 90 so that
    that's going to hopefully you're gonna
    like that okay it snaps to 90 and I can
    move on and I'm just all I'm doing is is
    undrawn lines and it keeps on going
    if I press escape it stops us I'll do it
    again I'm going to click on a lion like
    I'm left clicking left clicking now what
    i'm doing here is i'm left clicking but
    i'm letting go of the mouse if i hope

    Watch video from 12:00 - 15:00

    yet so I'm clicking I've let go of the
    mouse clicking and so on so make sure
    you can just draw lines like that press
    escape to stop donors
    okay so make sure you can do that it'll
    pause the video and practice with that
    for a bit I can click on a line and I
    can delete this I'm clicking on a line
    with my left mouse button and all I'm
    doing is I'm just deleting it
    I'm hitting the Delete key on the
    keyboard okay like so what else can I do
    I can draw circles okay I can click on a
    circle there and that's its center point
    and then I'm just dragging it out and
    you're going well how come it's not
    asking for dimensions or measurements we
    actually do that later this is the nice
    thing about sketching a rectangle so
    it's a center rectangle there's its
    center point and I'm just dragging it
    out okay curves don't don't worry about
    trying to and become an expert at any of
    this just practice drawing all this
    stuff you know align let's draw an
    angular line okay if I press ctrl-a
    it highlights everything and then I can
    press the leash now let's try it again
    I'm going to draw a line I'm going to
    bring it over here snap to the
    horizontal snap to the vertical let's
    see can I complete now look look at this
    this is called object tracking
    I'm not having pressed a button there
    yet now what I do is I bring it here and
    I just highlight below here now what it
    will do is it will complete that square
    I click and then I go up to there okay
    and now just just just to notice
    something whenever I draw a horizontal
    line this little green box box pops up
    whenever I draw a vertical line this
    little green box pops up and these chaps
    are called relations so just be aware of
    that and you know if I have an angular
    line there's no green box but watch this
    okay I had a nice vertical snap and a
    horizontal stop and it doesn't know
    right so let's get down to business and
    how do I delete all of this I can okay
    and another thing and there the middle
    the middle roller or ball on your mouse
    if you roll it and roll it away from you
    it goes away if you roll it towards you
    it comes towards you'll have to practice
    that what am i Zoo I'm zooming now at
    the moment end and out zooming now let
    me see how do I plan I can remember how
    dry pan is that alkyne oh how do i pond
    with solder works I can remember anyway
    what am i doing on zooming out and

    Watch video from 15:00 - 18:00

    notice wherever I put this mouse button
    it zooms into there I'm zooming out I
    don't want to zoom over here so I put my
    cursor over here and I use oom over here
    like so in and out no I'm going to I'm
    going to zoom out a little bit I'm going
    to put my cursor up here and I'm going
    to highlight all of this I let go but do
    it again I click now I'm actually
    holding it from this time bring it over
    crossed all the lines and I'm Latin goal
    that I've hit the Delete key race you're
    going to have these these sketches
    printed out on a piece of paper and it's
    going right in front you but what we're
    going to do is we're going to draw this
    jackhammer e type shape though so you
    want to make sure that you're
    millimeters I get myself a line and I'm
    going to come over here now just a
    couple of things you want to be watching
    out for another press escape here I move
    a little bit too fast you want to make
    sure this up here that says exit sketch
    I'm at right now I'm in the process of
    creating a sketch we're in sketch mode
    if this says exit sketch it means you're
    in sketch mode okay so hopefully it says
    that if it doesn't and let's say you're
    out of sketch mode what you might have
    to do is you're going to have to create
    a new sketch and go back to the foam
    plane now this is a little a little step
    that confuses the [ __ ] out of people in
    my classroom and and you know so we have
    to go over we go over over all undef it
    kind of finally settles them anyway now
    let's go but let's go let's get down to
    business here 50 so what I'm going to do
    is I'm going to draw a line and I'm
    going to just start somewhere over here
    and look at what am I want the eye line
    that's 50 and that line there is like
    400 so let's let's get a close to 50 53
    we'll do it on a press escape what I'm
    going to do is I'm going to move that
    line just over to here and I'm going to
    draw the rest of it in a zoom out
    and I can't remember what it looks like
    but if you look at something like this
    okay let's go back and have a look yeah
    it's something like that now what I
    could actually do is I can grab these
    lines and move these lines notice as I
    as I grab this line that it doesn't seem
    to move in the horizontal and that
    vertical because it has a vertical
    relation and gaunlet ahead of myself
    there it only gonna confuse you too much
    I can move those lines around the place
    like so now if you do something like

    Watch video from 18:00 - 21:00

    this I'm going to leave that for a
    second just just just keep looking if
    you do something like whoops if you do
    something like that
    what point I'm at hold on a sec let's
    try this again I'm going too fast if you
    do something like this and yeah it's
    just that's just not great you know but
    what I want you to do is just delete it
    delete the whole thing and start again
    first thing I want you to do is get a
    line that's close to 50 around the
    ballpark of 50 and I want you to see if
    you can move us towards and the origin
    what we can also do is we can put a
    dimension on so I put a dimension on
    smart dimension I'm going to just click
    on the line and I'm going to click here
    and then I'm going to click there and
    it's going to say what do you want the
    dimension to be well it'll put in 50 now
    why am I doing this I'm doing this
    because I want to be kind of in the
    ballpark I don't want to draw a massive
    jackhammer I then have to scale it down
    because it gives us grief you'll see
    what I mean so this is kind of the light
    the the ballpark and size of the
    jackhammer there's 50 and then I'm jus
    mning in with my mouse and let's go back
    and have a look and then I'm going to
    draw the rest of it and I click on the
    line and I'm waiting until I can snap to
    that endpoint
    and then I'm gone I'm going out of my
    way to snap to the vertical and all I'm
    doing is I'm just sketching this I don't
    care about the dimensions what I'm
    concentrating on is getting those those
    lines to be straight okay I bring my
    cursor out and then I object track to
    that point I don't go too far I bring it
    back and then they come up I want to
    have - I don't have any extra lines in
    there that I don't need if you have any
    extra lines delete them once I have this
    I'm going to start adding some
    dimensions now what is this going this
    is five so I'm going to put a five there
    okay I'm going to put a five over here
    all I'm doing is you're ready think of
    yourself that's a little bit obsolete
    you know but what I'm going to do is I'm
    just trying to show you how to draw
    lines and add dimensions we're not going
    to get too sophisticated too quickly
    what else so I need 25 smart dimension I
    click here and I'm pulling my dimensions
    away from the object 25 20 whoops not
    zero

    Watch video from 21:00 - 24:00

    hopefully I'm not going too fast for you
    20 okay what else do I need another
    smart to mention I put one on this side
    of 20 and this is 50 now what's this guy
    think this is 10 here so we have 10 so
    from there to there is 10 now what's
    this dimension so from okay another
    thing when you're putting your
    dimensions always go from a line to a
    line never a point to a point now this
    is going to be 20 okay now if this is 20
    and that's 10 this is going to be five
    okay now I have all my most of the
    mentions I need there this looks pretty
    good it looks actually quite close to
    this okay no okay let's have a look do
    we have everything
    so there's my first sketch and I want
    you to notice a few things we have the
    blue lines we have the black dimensions
    and we have the green relations what are
    these things called the called relations
    what does this say it says that this
    line is always going to be horizontal if
    I try and grab that point or try and
    grab that line and move that around it
    always stays horizontal if I click on
    that relation and press the lease and
    then I grab this point here uh-huh I
    like relations that now I can do now I
    can rotate it and do stuff with it okay
    so how do I add a relation I can click
    on the line and on the right hand side
    here I have line properties and I can
    add a relation so I'm just going to add
    a horizontal relation there okay no okay
    now these lines are blue and the reason
    that they're blue is SolidWorks is
    telling you that these lines are called
    they're under defined okay so we need to
    somehow
    we need to tie this into the origin so
    there's your origin there the zero zero
    point I need to somehow tell you this
    sketch into that's not a good
    explanation I need to I need to lock it
    in somehow so I need to lock it into the
    XYZ space there's an awful lot of
    different ways of doing this and one way
    I can do it is I'd rather not tell you
    the I'd rather just tell you the best
    way of doing it and then you can learn
    we can I can teach you the bad habits
    what I'm going to do is I'm going to I'm
    going to put I can pick either this line
    or this line and I'm going to put it as
    a midpoint on that origin I it doesn't
    matter I'm going to pick this plane and
    I'm going to hold down the control key

    Watch video from 24:00 - 27:00

    because all to select multiple things
    and I'm going to click on the origin and
    I'm going to click on midpoint and what
    does it do it makes this line always a
    midpoint to that origin and notice how
    everything else is after going black now
    I know you're confused I'll give you
    I'll give you a little example it's
    going to delete some of these dimensions
    now notice as I'm deleting dimensions
    stuff is going stuff is going blue okay
    because it's it's under defined no so
    let's have a look this line is black
    it's completely defined because it's
    locked into the midpoint and it has a
    dimension okay this line is part of it
    as black but this part of is blue
    because there's some dimension missing
    now I kind of don't again if you this
    right now but what I want you to do is I
    want you to remember two things I want
    you to typically lock one of your
    horizontal lines to the midpoint of the
    origin I'm going to keep on doing that
    and the second thing is by adding
    dimensions by adding the mate relations
    we can make this fully defined you're
    probably I know you're confused
    believable I'm going to keep going so
    I'm going to make this 20 that goes
    black
    I'm going to make the dimension of this
    line 20 that goes black what else nope
    why is this and we want this to be 50
    don't we
    let's make this 50 okay this is all
    that's not meeting another dimension
    what's this 25 there's a 25 user yep
    this is 5 this is 5 like so okay now
    notice how all of these lines run black
    because they're all they're all tied
    back to this original line this line is
    locked in and then we lock in this line
    because of the 20 to the 20 dimension
    this line gets locked in because of the
    25 and then this line gets locked in
    because the 5 now if I remove this
    dimension all of it goes blue because
    it's all under the finds so let's pull
    them back in and I remember I'm going
    from line to line okay now all of this
    is blue I can grab us and I can move us
    I can grab this line it doesn't go
    anywhere because it doesn't have a
    choice it's locked in by its dimensions
    now if I make this dimension from that
    line to that line 5 it all go black
    because this line has a dimension out to

    there of 20 and under 50 so hopefully
    you're not too confused but anyway so
    that's the first sketch um so you're
    learning some new concepts a fully
    defined sketch and relate you know
    relations are you have dimensions and
    then you have the lines this is just a
    sketch okay and I'm going to I would
    give you about nearly 20 minutes there's
    a lot of steps and a lot of little
    idiosyncrasies that students need to get
    our head around and little steps that
    they need to learn
    and so we can move on to the next sketch
    so let's have a let's let's start this
    second one here okay so on on the sack
    and what does it look like it's it's I
    don't know an H so it is H with a
    rectangle in the middle of it and so
    what are we going to do we're gonna go
    back to solder works I'm going to press
    X to get out of here
    don't worry about Savin or just
    practicing I go new part I want to
    change firstly I'm going to change this
    to be millimeters I'm going to click on
    sketch we're going to create a sketch on
    the phone plan and let's have a look so
    we have it looks like it's easy by about
    fifty is there is the size of it so
    let's go back another look so under draw
    here hope that's that's roughly eighty
    eighty five eighty it's also it's close
    enough
    I'm just going to draw this this H
    business I'm going over my way it's two
    to use all those horizontal and vertical
    snaps and then the next thing I'm going
    to do is I'm going to get an A Center
    rectangle and I'm going to lock the
    center of this rectangle in with the
    origin and I'm going to draw like so
    okay now let's let's let's be careful
    here
    so you'll notice I have two new and I
    have two new relations these are two
    midpoint relations on that rectangle so
    it's just let's let's go back and let's
    add some dimensions here so I'm going to
    go from that line to there I'm going to
    make that Asian and I'm going to have
    fifty from that line there to that line
    there is fifty
    okay we're going to show you something
    new I want I want this this the length
    of this line is AG as well now I don't
    have to put in two dimensions and have
    to change two dimensions each time but

    Watch video from 30:00 - 33:00

    what I can do is this I can make this
    line line up with that line so wherever
    this line goes this line will follow us
    so how do I do it ah Sh I click on one
    I'm sorry I click on one lion I hold
    down the control key on my keyboard I
    click on another line and what do I do I
    go collinear okay now watch - so
    wherever this Lane goes the other line
    follows I make this line hold down the
    control key make sure that I select us
    make sure I select the other one and I'm
    going to go collinear now what's the
    length of this line no the length of
    this line is 80 because it's the same as
    that one because it's both they're both
    tied in hopefully that's all I collinear
    is a very useful relation now you know
    four types relations you know and
    midpoint let me see if I click on up
    does it tell me what type what type it
    is if I just highlight overs no excuse
    me for a sec okay this is a collinear
    that's horizontal that's a vertical and
    that's a midpoint relation so now you
    know for them kind of what else we need
    to do and we have 10 30 and 10 so let's
    do it I'll do it on this side 10
    30 and 10 whoops it doesn't like that
    way it does it doesn't want me to do
    that because I have a 50 here so the
    distance from there to there is 50 the
    distance from there to there is 10 the
    distance from there to there is Turkey
    it already knows that this is 10 you're
    giving it an extra dimension what you
    can do is I can delete this 50 I can add
    that 10 in there what I was doing
    there's or something called over to
    finding a money I don't want to get into
    it now for the time being and okay
    that's how they look here what else do I
    need
    and I need a 15 so from that line to
    there is 15 what else I need add 30
    under 20 so this here is 30 and that
    there is 20 now notice how this
    rectangle goes black why is it going
    black because the center of it is locked
    into where the origin is and it has all
    that matches that it needs you know so
    this that rectangle there is fully
    defined okay so I'm just going to pull
    these dimensions able to make it a
    little bit neater hopefully you're not
    too confused what's the dimension from
    there so from there to there is 10 and
    from there to there is 10 remember on
    going from line to line always line tool

    Watch video from 33:00 - 36:00

    items
    okay so I need I'm going to go from line
    to line again the hot bag was a little
    break there in the record and so
    hopefully it's not too confusing um I'm
    just adding the dimensions like I was
    doing without someone missing I know
    that this is a G and I know that this is
    50 so the distance from there to there
    are there to there is want to be 15 so
    let's put that in from line to line well
    nothing I can do is impress and escape
    there's I could put a dimension in the
    dot line it'll make that 15 and all of
    these lines go black now what I can do
    is I can grab this and it I can move it
    okay so that's not fully defined
    everything else is defined apart from
    the blue lines so why is why isn't is
    what I can do is I can
    it needs a dimension basically or needs
    relation I can put in a 10 there and I'm
    it goes black don't think I can do is I
    can click on this line and click on that
    line and I can make them call in your so
    wherever the position of this line is
    it'll be the same with that line I'm
    just going to do the same here as well
    I'm going to make that collinear now
    what else can I do here I my dimensions
    are kind of untidy so what it can do is
    I can position them and make kind of a
    little bit neater so anyone else that
    has to work with your drawings or work
    with your parts you know everything is
    neat and it's organized so what do I
    want you to start thinking about and a
    fully defined sketch has all the
    dimensions that it needs that's one
    thing it's tight somehow tight into the
    origin that's a second thing and the
    third thing is it has relations okay and
    if you have blue lines some blue lines
    you're missing dimensions or you're
    missing relations and okay that's the
    second sketch so if you've something
    like I have here or it's pretty close
    we're in business you know you're going
    to have cover this in class or a hope
    are going to be fine with this okay
    let's move on to the next one so I'm
    going to press X and get over here I'm
    going to go don't save and let's have a
    look at the next one can I get rid of
    this here this stuff on the right hand
    side I don't think so all right let's
    look at sketch number three so the new
    stuff here that you're saying is we have
    circles and what we're going to do is
    we're going to keep all the units as
    millimeters but what we're going to do
    is the origin is going to be that point
    right there
    so we've two circles the first circle
    has a diameter of 30 the second circle
    has a radius of 30 but its diameter is

    Watch video from 36:00 - 39:00

    going to be 60 so you have two circle
    let's draw two circles first we go new
    you're not going to get that error I've
    just screwed up my solder works on my
    computer you're going to go apart you're
    going to go okay we're going to change
    this to be millimeters we're going to
    create sketch click on sketch we're
    going to click on the font plane I'm
    going to draw two circles okay now I
    just want a normal circle notice how I
    can hit this drop-down button and I can
    get different types of circles I can
    click this drop-down line I get
    different types of line so anyway the
    normal circle I'm going to lock its
    center point of the circle to the origin
    and I'm just going to draw one there I'm
    going to get a second circle and lock
    its center point now you're looking for
    that change of icon I'm gonna draw a
    second one no the first one has a
    diameter of 30 so I click on the edge of
    the circle and I'm placing my circle
    diameter out here and what do I want I
    want it to be Turkey like so and then
    I'm going to move this in a little bit
    closer the next circle has a diameter of
    60 like so now I don't like how that is
    dimensioning so I'm going to delete that
    type of dimension and I'm going to go
    back and do a smart dimension will pay a
    little bit more attention I don't like
    that
    I'm going to move it up a little bit and
    I'm going to get my typical circular you
    know damn her leader type dimensionally
    that plugs make any sense you would I
    like the way this looks
    no let's go back and let's have a look
    at this thing these these points here at
    12 o'clock
    and at 3 o'clock at 9 o'clock and at 6
    o'clock
    are called us called the circle
    quadrants we're going to we're going to
    start aligning about three o'clock
    quadrant we're going to go celled we're
    going to come over and we're going to
    draw this now let's see if I can
    remember this so we start there we lock
    on to that quadrant and I come down I
    come over I come up and it's something
    like this and then I come over what does
    this call is called object tracking so I
    go I'm not clicking anything here I'm
    zooming in I'm just I'm just what am i
    doing I'm hovering over that quadrant
    point I'm not clicking anything I'm
    going to go I'm kind of Santa SolidWorks
    wakey-wakey I want you to remember this
    point now watch this I'm driving along
    my car and buying it remembers that and
    now I can object track up to that point
    that's going to take a bit of practice
    ok now even I can remember that this
    dimension here is 150 now I'm zooming in

    Watch video from 39:00 - 42:00

    and out I'm using that roller bar to
    zoom in and out around my sketch that's
    also going to take a bit of practice now
    what's this height here 25 I can
    remember the 20 like I remember the 5
    there's the 20 and they can remember
    this 5 I'm going to put that in there
    just line to line now do you remember
    notice that this line lines up with that
    line what is that called
    remember loss if I click on one line I
    hold down the ctrl key and then I click
    on the second line what do I have here I
    have horizontal vertical collinear
    collinear looks good let's try it if I
    click on collinear and let's say it
    didn't work out
    was something I didn't want I want to
    undo us I just press control of the a
    not will not do it for me
    now another another to match you're
    missing here from what I can do I can go
    from the line to the circle and I can
    make not 40 or I can just click on this
    line itself not line there is 40 then
    okay now we're missing one more
    dimension 35 to more 35 and 25 pretty
    sure that's about 35 maybe not yep and
    this one here is 25 okay what do I do
    i tidy up my dimensions make them nice
    and nice you know don't have them
    cramped in there amongst there and try
    and have them outside of the shape don't
    have them open that's the line pull them
    out a little bit okay now I have a
    circle here and it goes all the way
    around but in this example it doesn't it
    breaks it's just a semicircle so what do
    I need to do if I click on that circle
    and I press the Delete key I lose the
    whole thing so what do I didn't know
    what press ctrl-z to undo my screw up
    the new word that you're going to learn
    is called trim now if we drop down this
    next let's hold on a sec let's just
    click on trend and there's five types of
    trim five different ways of doing it you
    only need to know one and its power
    trend okay so make sure power trim is
    highlighted I noticed when I click that
    there is a little gray line wherever
    that gray a lion touches on going all
    over the place as soon as it touches not
    it removes whatever is there now it
    removes between those why does it what
    how come it does it remove the whole
    thing because it no it sees that there's
    an intersection there and an
    intersection there okay so they've
    already set those intersections so I'll
    go trim and I start around here and as
    soon as I cross that line it gets rid of
    us
    it cooks it away trims us up to where

    Watch video from 42:00 - 45:00

    each of the intersections are and that's
    what trim does it removes a section of
    the line let me just let me just show
    you that again all right so it could
    have whoops there's a line and here's a
    circle okay now let's say I want to get
    this bottom half away I have an
    intersection there and an intersection
    there so I'll get the trim and watch
    this then we'll just cut that and it
    will do the opposite in the other side
    now what happens if I do here and you
    just caught up to where the intersection
    is like so okay so that's what trim does
    you're gonna have to practice that a
    little bit more when we keep with keep
    on using it for the next couple of weeks
    and it's all fully defined and a couple
    of things this new thing this new
    relation that was automatically added
    that's called the tangent relation I'm
    going to get into that a little bit
    later but what SolidWorks will do is
    will automatically add relation
    sometimes which can be a good thing but
    it can also be a bad thing this is a
    fully defined sketch why is it fully
    defined if I try and grab a line or try
    and move it around it's it's it's static
    it will not move it has enough
    dimensions and it has all the relations
    that it needs
    okay that's the third sketch okay so
    we're starting to get somewhere
    the fourth sketch now you're probably
    thinking when are we going to get into
    this tree to three dimensions these
    solids forget about it for a couple of
    weeks you're going to have to just soak
    up the 2d route for another little bit
    so what we're going to do is we're going
    to do this shape here okay and one
    sketch number four so I'm going to take
    this a little bit slowly and just kind
    of go over a lot of the stuff that we've
    that I've kind of introduced so what do
    we doing we're drawing two circles and
    it looks like a grandfather clock kind
    of shape and the only thing that's new
    is we have these little curves and here
    and four little curves these are called
    Phillips
    and they're little they're little curves
    you see them an awful lot in engineering
    so but what are we going to do I'm going
    to press X to close this down I'm going
    to go don't save and I'm going to go new
    a new part okay sketch create a new
    sketch credit on the front plan and
    let's go back here another look so what
    are we going to do we're going to draw
    both of these circles and the damn are
    60 and the damanhur 90 radius 45 but a
    demurrer of 90 and there will be locked
    into this center here so this is going
    to be our origin oops let's try that
    again okay now what's happening here I'm
    trying to draw something and I'm in

    Watch video from 45:00 - 48:00

    inches so let's let's delete that let's
    swap this inches to be metric and then
    we're going to create a new sketch again
    on the phone plan so what is that radius
    let's just draw two circles I'm going to
    be locked in to where that origin is the
    center point of the circle is going to
    be locked into the origin now I try to
    remember what it was 60 and 90 so this
    is that diameter of 60 and this is going
    to be a diameter of 90 now again I don't
    like the way that thing is dimensioning
    so I'm going to delete this and I'm
    going to reduce not like this but like
    this
    there we go I'm a bit and I'm sorry
    obsessive-compulsive you actually need
    to be a little bit when you're when
    you're drafting anyway anyway Downers
    Dahmer 60 and ammeter lady now there we
    go now we're going to work from these
    quadrants again and I'm going to draw
    the rest and I'm gonna draw this in and
    I'm going to add in add in the fill its
    laver so let's zoom out a little bit
    let's look into this origin come down
    over
    and it looks something like this and all
    we're doing our very best to get those
    no what happens if I'm after if if I'm
    after screwing up a little bit I can
    also grab that point and I can just move
    it over like so and I'm going to draw a
    line down from from this quadrant and
    move it down and I'm going to stop when
    it what an object trucks at that point
    like so and then what am I going to do
    then I'm going to grab this point and
    I'm just going to drag it over and I'm
    just going to merge them two together
    now now watch this now I grab this and
    now there there is one okay so we kind
    of have a pretty okay sketch we got to
    start adding some dimensions now and if
    you've screwed screwed up parts of us
    just highlighters and alesis now I want
    to show you I want to show you something
    here for a sec I want so I'm zooming out
    a little bit and I'm coming up here and
    I'm going from the left to the right
    notice how the box is blue and then I'm
    going from the rice to the left
    no I said the box is green okay so
    that's how let's try this if I'm here
    and I start here and I move over notice
    that it's a blue box now what is it
    going to highlight if I let go with a
    blue box it highlights anything that is
    totally totally within the blue box so
    what it's going to do is it's going to
    highlight these two circles and these
    two lines let's try it again and I let

    Watch video from 48:00 - 51:00

    go it just highlights whatever's in the
    box let's try it here what is it going
    to highlight it's going to highlight the
    tree lines the two vertical lines on the
    bottom horizontal line like so what
    about here what's it going to highlight
    is it going to also going to highlight
    it highlights nothing okay so that can
    be kind of useful you can go in there
    and you can highlight certain things now
    watch this that's gone from left to
    right because it's blue now if I go from
    right to left it's green the thing with
    green is it'll highlight whatever
    towards you
    the green box now what is it going to
    highlight in this it's going to
    highlight the two circles and the heart
    on the vertical line like so okay I'm
    all from left to right right buy more
    from rated after it's green whatever
    touches the green box is what it's going
    to highlight that's very important it's
    very very useful no let's go back so we
    got we got the 70 we got to 20 so the 70
    goes to this bottom line and then the 20
    brings it over
    excuse me so I'd only go from point to
    line I'd rather go from a line to a line
    so I click on the outside of the circle
    I click on this line now is it being
    cheeky with me let's try that again
    there we go so we want this to be 70 and
    we want this line from that line to that
    line we want that to be 25 now let's
    have a look we write 20 okay now what am
    I going to do I don't have to put in
    another another 20 dimension here and
    what why is that because when you get
    really good at solder works what you're
    going to be doing is you're going to
    drawing up all these parts and you're
    going to show them to your boss and your
    tinker done and your boss is going to
    say I like that John but I want you to
    change this this this is the string of a
    hundred things to change now if I have
    to change the shape and I want to let's
    say he says or the boss says that this
    is it's not disparities and taken off
    and it's going to break if I have to
    change this 20 then I have to also
    change that 20 let's have to make this
    25 also have to change this to be 25 now
    there's a chance that you forget that it
    will be nice if we could set this so
    that whatever thickness changes here
    it's going to change it on the other
    side so we use we use relations you want
    to make it you want to make your model
    smart and you want to make things to be
    easily modifiable if that's even a word
    nope I'm going to click on this line
    holding the ctrl key
    click on this Lane and I'm going to go
    call in yer I want to click on that line
    at this line
    I'll make them call in your you like
    that let's go back and we'll change that
    to be 20 and notice how it changes now

    Watch video from 51:00 - 54:00

    what do we have we have 250 from that
    edge to that edge there
    excuse me so I'm going to go from that
    lion to that line and I'm going to make
    that 250 like so and like this it's
    after crapping out a little bit so I'll
    just grab that line and move it over now
    why why is this still moving okay it's
    still moving because it's not related to
    the origin and I'm going to show you a
    better way of doing this board just I
    want you to just soak this up for now
    what we're going to do is we're going to
    put a dimension in from that line to the
    center point and instead of clicking on
    the center point I'm just going to click
    on the circle and it will lock to that
    center point anyway and what are you
    going to do we're going to make this a
    hundred twenty-five okay and not hundred
    twenty-five locks that line in and then
    it locks that line in I want you to
    start thinking about this whole concept
    of a fully defined sketch and why are
    your lines turning black where they do a
    lot now what else do we have we have a
    little dimension here of three so on the
    reporter dimension it from that line
    remember line to line and let's put this
    in is three now what else we miss at 25
    and again I'd have to put another 25 on
    this side but what I can do I can make
    the length of this line equal to the
    length of that line how do I do it
    again how do i how do I add a relation I
    click on one line hold down the control
    key click on another line what do I have
    I have there already called linear I
    don't you park in perpendicular there
    already parallel maybe equal let's try
    equal now what it does is it whatever
    this if I change that to be 50 look what
    it does another side
    what makes things easy so these
    relations are nice now let's go back to
    the this this section of the circle is
    trimmed away
    so I go to trim I like my power trim and
    I just start over here and I start
    calling it now I could start on the
    other side and I just coats it away
    subtle trim does no are we missing
    anything we're missing the Phyllis now
    where is that I can't see it anywhere it
    must be here somewhere where is it it's
    right there sketch Phyllis what does it
    do it rounds the corner at the
    intersection of two sketch entities now
    you've seen an awful lot in engineering
    because you're going to be making these
    metal or these plastic parts and we
    don't want all these sharp edges to the
    coating on people's hands
    so what you'll do is you will you'll
    corner those sharp edges okay now what
    is the Phyllis in this Phillip size is a
    radius for typical that means all
    wherever you see a ray of Phyllis or

    Watch video from 54:00 - 57:00

    radius it's four so what do we do we put
    it in here
    Phillip parameters it's 4 notice how I
    have a pin here I'll go back to that
    every second and i zoom in I'm going to
    go from that edge to that edge and I'm
    going to go OK
    all right I have the pin keeps this
    visit visible I go from that edge to
    that edge and I go okay and then I go
    from that edge to that edge okay
    now if I get rid of this pin here look
    what it does if I do one of them buying
    line-to-line sorry and I go okay it just
    goes away but sometimes you have to do
    multiple Phillips now there they all are
    we have four Phillips now you're
    probably how can we I don't always do
    the way that we can actually make them
    equal lever let's trace if I click on
    that curve and that curve can I make
    them equal that's nice there that's
    that's good okay so we'll do that let's
    click on let's delete all those
    dimensions and let's make click on the
    curve zoom in here click on this curve
    we'll make it equal oh I'm doing lots of
    zooming in and out here with my
    rollerball I'm holding down the control
    key and I'll make that equal now look
    what happens let's say your boss says
    that Phyllis isn't big enough it needs
    to be bigger I can click on one of them
    now and I can I can change one of them I
    will change them all like so okay so
    what is this this is originally for
    let's have a look at this what do we
    what have we just what if we just shown
    you there we're amount for going over
    trim I'm after showing your sketch
    Phyllis everything is black because it's
    fully defined let's say you're very very
    proud of this and you want to save how
    do we save what you're going to do is
    when you're going to on your your
    computer or on your your workstation the
    college there you're going to have a
    directory or a network location it's
    going to be it's going to be I think
    it's the H Drive on in the computer on
    your workstations in the lab anyway what
    are we going to do I want you to
    right-click and I want you to create a
    folder wherever you actually want to
    save and you're going to call this e and
    T two six zero space
    SolidWorks okay and in there we're going
    to have lesson one
    I want you to have lots of directories
    lots of folders I want you to be
    organized now let's go back here and I'm
    going to go exit sketch and I'm going to
    go file save us now and sort of works

    Watch video from 57:00 - 60:00

    the SolidWorks filing stuff this
    desolder works file extension is done
    SLD PRT it's a subtle works part and
    what we going to call this we're going
    to call it something logical we're going
    to call this lesson one part four and
    that's this you're have to save in your
    work so I close it down I'm going to go
    open and there is okay that's it okay
    let's show you the next one so we're
    done with - this is a bit of a beast so
    this one's going to be interesting I
    need to take a need of a bowl of
    cornflakes before I move on okay okay
    but um what are we on now we're on
    sketch number five so let's let's let's
    give it a lash and my feeling is we need
    we need to decide where the origin is in
    relation to this shape and you could put
    it anywhere you could put it there at
    that point you could really put it
    anywhere but the logical place will be
    either at the center point of this curve
    or the center of the two circles what
    I'm going to do and there's kind of a
    reason for that I'm not going to expect
    there's kind of reasons but I want to
    show you that this these tangent lines
    later so what we're going to do is we're
    going to start here right there that's
    where our origin is going to be and we
    are going to draw a full circle now the
    full circle diameter is can you tell me
    what it is in your heads it's the 60 -
    the 40 so it's 20 from there to there so
    we need a circle with a diameter of 20
    so let's start with us so let me just
    move this guy over here and let's start
    so what do we do we go new part okay we
    change this to be millimeters we create
    a new sketch and we put it on the phone
    plan so there are your steps like going
    to grab get a circle and I'm going to
    lock it in to the origin the center
    point to the origin and what is the down
    but our going to be so its diameter is
    going to be 20 and we have that okay
    let's go back so at the 12 o'clock
    quadrant we're going to come out and
    we're just going to draw on this bit of
    a lion-like so I'm just going to sketch
    it in so I'm going to lock into that 12
    o'clock quadrant or I'm just going to
    bring it out and come up and come over
    I'm not worried about the dimensions I'm
    just just sketching it and I'm going to
    do the same over here I'm going to lock
    to this quadrant I'm going to come over
    and down like so now what relations can
    I add kind of quickly they would make
    life easy for me in this drawing this
    line and this line when I said drawing a

    Watch video from 60:00 - 63:00

    protein trying to confusion I should I
    should be using the proper terminology
    in this sketch this line and that line
    are and collinear so let's do that
    I click on one line holding the ctrl key
    click on the second one excuse me I
    click on collinear and adds the relation
    now if I grab one of them they both
    travel together
    and I know that this dimension here is
    20 and if you want to show off we can I
    click on this line on that line and we
    make them equal as well okay and let's
    look at the distance from here to that
    line is 20 so I'm just working through
    what what I'm doing from the complicated
    go is you might have seen me before I'll
    draw the entire shape out and then I'll
    artists I feel like was something a
    little bit more that little bit hairier
    I like to build it up slowly so I'll
    draw sections of it
    in our dimensions and kind of build up
    in baby steps that's kind of how I walk
    myself and it seems to work so I'm going
    to add from the set from the circle out
    to the edge or make that 20 like so and
    now what's next let's trim this bit of
    it away power trim and we just get rid
    of that child now before we draw those
    uh those angular lines then let's get
    the circle that's over here now I'm just
    going to put that circle in I'm good I'm
    actually going to put us I'm going to
    put it out away and I'm not even
    lighting it up so I want to show you
    something we what what is the size of
    this this chap here it's the circle says
    radius 10 but the full that the full
    circle is going to be a diameter of 20
    that's kind of hard normally explain
    that well so I'm not I'm not explaining
    it well whenever you have a full circle
    360 degrees you always have a diameter
    symbol whenever you have anything that's
    less than a full circle it would always
    give a radius hold on but what we're
    doing here is we're drawing the full
    circle in and then we're trimming it so
    we need to put in a diameter of 20 so
    let's do that a diameter of 20 that's
    another enough so I have the diameter of
    all of them 20 on my circle nuts and
    that's another issue that students have
    a little bit of a trouble with is this
    whole concept of them radius and
    diameter so the diameter is just it's
    just twice the radius you know and
    hopefully you've covered that in high
    school now and what do I need to do I
    need to line up this if we go back to

    Watch video from 63:00 - 66:00

    that whoops if I go back to this you can
    see that this circuit here is lined up
    there across a horizontal so how do I do
    that I can click on the center point of
    that circle I can hold down the control
    key and
    click on that origin or the center point
    of that circle and I can make them
    horizontal to each other so I try and
    grab the circle and move it and it's
    locked to the horizontal know what is
    the dimension from whoops let's zoom out
    here for a bit
    what is the distance from that point to
    that point there it's 60 so it's the 80
    minus the 20 so I'll click on this this
    circle and I will click on that circle
    now what does it do it gives me that
    dimension from the center point to the
    center point that's what it does I'm
    going to make that 60 like soap now
    watch this and let's get the last thing
    in the 40 so let's get the 40 dimension
    in before they show you that the tricky
    bit 40 I'm going to make this line this
    line and that line equal to one another
    and notice how everything is turning
    black because I'm slowly building it up
    and we want a fully defined sketch no
    these lines are the angular line that
    has a tangent relation and a tangent
    relation to the circle what does that
    mean it means it torches it at just one
    point now so let's go back and have a
    look at this if I go from there to there
    is that what is that what they want what
    they what they want is this has a
    perfectly smooth transition okay there's
    no break there like I have okay so this
    is not a perfectly smooth transition
    what they want is something that looks
    like this it just it just touches it
    that's worked at one place okay so how
    do you do and you can you can if you if
    you kindly are careful with you kind of
    moving along the circle and notice how
    that that light that I can't change is
    it's not tangent no it is okay okay but
    what it does is it actually it's still
    not so what we're going to do is we'll
    do this we're going to draw the line
    in there and I'm actually I'm actually
    intentionally I'm going I'm going out of
    my way not to get anywhere near that
    tangent point and all I want to do is I
    want a coincident point what the hell
    does that mean
    now we'll have a coincident relation
    there that means that the line will
    touch the circle okay now watch it okay
    that's a coincident mesh
    okay I'm grabbing that point I'm just
    moving around okay so that means that
    the end that line will always touch the
    edge not circle that's called coincident

    Watch video from 66:00 - 69:00

    and that's what I want and I want to
    have - I click on the circle I hold down
    the control key and they click on the
    line and then I come over here and I can
    add a tangent relation okay so what I
    have two relations that will have a
    coincidence relation and I have a
    tangent relation like so so let me do
    that again so I start over here I lock
    on to that point I go out of my way to
    kind of keep away from the quadrant
    points to lock that in or and the
    tangent point I'm just getting a normal
    coincident major and then then I check
    it and I know that it moves around then
    I click on the line
    hold on the control key and then I click
    on the circle and I click on tangent and
    now I have a tangent mate or a tangent
    relation I'm sorry now that's going to
    take a bit of practice and I know you're
    going to have to help you with that but
    it's that's no big deal now what's next
    I'm going to trim this bit of a circle
    away and now I'll have that edge now
    what are we missing here we're missing
    this little hole that's there the hole
    has a diameter of 12 okay so what I'm
    actually going to do is I'm going to
    click here and I'm going to lock into
    that point right there and then I'm just
    going to draw this in and then I'm going
    to add its dimension and what is it it's
    the diameter of 12 like so
    it's not pretty tricky now what are we
    missing here the only thing we're
    missing are these four four holes for
    some reason or not or not there we go so
    we have the dimensions of 30 and 10 and
    what else
    10 it's I don't think they're actually
    giving us that one down or 10 for plates
    so what's this what I'll do is I'm going
    to draw in just four circles one I'm
    just sketching them in there just drawn
    them in okay and there's no dimensions
    on the MER anything I'm going to click
    on the edges of them one edge and I'm
    going to hold them the ctrl key and I'm
    going to select them all and what am I
    going to do I'm going to click on equal
    alright and then I'm just going to
    mention one of them up number 10
    now what happens they're all 10 no I
    like that okay now the dimension from
    there to there is going to be 10 all
    right and notice when I grab the center
    of this circle it doesn't move it only
    moves to the left and the right because
    it's missing a dimension what I'm going
    to do is I don't have to put in another
    10 for this guy I'm going to make the
    central - and the center of that wash
    horizontal and we'll lock them in I'm
    going to make the center of this and the
    center of that horizontal to one another
    I'm going to make this point at this

    Watch video from 69:00 - 72:00

    point vertical at this point and that
    point vertical now what are we missing
    we're missing this 10 here so I'm going
    to go from that edge to the center are
    they going to make that 10 and that guy
    it lines up as well now this this circle
    goes completely black it has nowhere to
    move it's it's fully defined okay all of
    these other lines have already been
    predefined we've done that and once you
    lock into those edges it's gonna lock
    this in if I delete
    - equal relation it's blue again why is
    it blue because it's missing a dimension
    so all I can do is I'll just go back and
    I'll make it this one equal to - I have
    a feeling you're you're probably getting
    a bit confused with this fully defined
    sketch awfully you're if you're not but
    if you are and we're just going to keep
    on working through it and hopefully the
    penny will drop but this concept of a
    fully defined sketch is critical it's
    extremely important now what dimension
    are we missing you're missing that the
    30 so we go back I'll go from there to
    there and we make that 30 and that goes
    black now what are these two blue let's
    grab one of them are missing a dimension
    so what is it I need to click on this
    edge to the center of the circle but
    I'll give it the ten that it needs and
    now it all goes black what else can I do
    here it's a fully defined sketch let's
    just clean up your dimensions tidy up
    your dimensions a little bit and make
    sure that they're not rubbing up against
    each other and let's give them a little
    bit of space that's a pretty tricky
    sketch so you can see why I just stick
    it I stick with the 2d for a couple of
    weeks you know what I mean really
    there's there's enough confusion with
    these transient relations and trimming
    and Phillips and so on so that's it
    that's the second sketch okay so what's
    the next one look like sketch number six
    so we've only - and sketches left sketch
    six and sketch seven and typically it
    takes about a full class it may take us
    three or four hours to actually get
    through all of these and then you're
    going to homework to do as well so let's
    let's go to sketch number six and all
    right let's have a look
    what do I do I create a new part the
    changes to be millimeters and let's have
    a look I want to create a new sketch on
    the front plane and let's go back and

    Watch video from 72:00 - 75:00

    have a look at this thing here where do
    you want to put the origin where is the
    origin going to be in this this sketch a
    good place will be right there
    so let's draw and this is this isn't a
    very good example but we're going to
    let's let's keep going with it with 25
    and we have a diameter 25 and we've
    radius of 15 so 25 and 30 okay so I'm
    just going to draw two circles really
    quick and I've locked both limited on
    origin now what is it the first one is
    going to be 25 and the second one is
    going to be 30 let's move them in a
    little bit why how both of these circles
    gone from blue to black they've gone
    from blue to black because both of them
    are fully defined the center point is
    locked into the origin and they have a
    dimension so they go black and so let's
    get these two lines here now the 25 so
    I'm going to lock into there or is it
    the 9 o'clock quadrant press escape and
    lock into the three o'clock quadrant and
    then watch this I'm going to highlight
    both of them like this and I want to
    just make them equal okay I'm going to
    click on smart dimension zoom in and
    make this 25 okay
    where both of these locked in because we
    lock them into that quadrant we've given
    them a dimension if I try and grab them
    a move and they won't go anywhere now
    what is this this is like an upside-down
    Y so see let's see if I can draw this
    out so we're just going to sketch this
    bit of it
    okay what I'm not what I'm actually
    going to do is I'm going to I'm going to
    make this a little bit crooked I'm going
    to I'm going to intentionally mess with
    this it looks something like that
    I know it's not right but what can I do
    I can make what let's have a look these
    two are parallel and these two are
    parallel so let's let's start with that
    let's make you and you I'm holding under
    control can all gone a bit fast no I
    make those two parallel I'll click on -
    hold on the ctrl key click on that make
    them parallel okay and I'll make this
    guy bat align horizontal I'll make let's
    have a look go back this is 90 degrees
    and that's 90 degrees 90 and 90 so I'll
    make that perpendicular oh yeah let's
    watch that just for a sec and okay see

    Watch video from 75:00 - 78:00

    what the problem is with this is this
    we've automatically pulled this vertical
    relation in so that's delicious
    well hey let both of those I'll make a
    perpendicular there we go
    highlight both of those lines and make
    them perpendicular how they've both of
    those make that perpendicular and make
    that perpendicular okay now we know that
    that's 12.5 and we know that that's 12.5
    so we get a smart dimension okay it's
    not that it's not a type of dementia
    nuts let's get it let's get it right
    it's in a lying dimension so it's not
    it's not a vertical or horizontal it's
    aligned we make a 12.5 we'll make this
    line and that line equal
    okay so I feel like we need an angle
    here this if there's an angle missin
    okay we have 135 okay an angle so I get
    a smart dimension I click on one line I
    click on the other line and that allows
    me to put an angle in between them okay
    so this angle is 135 135 degrees on an
    angle from there to there so hopefully
    you've done a bit of geometry in high
    school and you're not learning a lot of
    this from scratch because that would be
    that will be tough no we have a
    dimension here of 60 from the center
    point down to that point so from there
    clicking on the edge of the circle and
    bringing this over and getting a nice
    vertical dimension of 60 and this is a
    sama this so if I click on that point I
    hold down the control key and I click on
    that point and I make them horizontal
    that lines up now I feel like there's a
    dimension missing on our original
    drawings we don't know what the height
    of this is so I'm just going to make it
    40 I'm going to make it from the center
    of there to there we're just going to
    make it 40 or missed it's actually
    missing a dimension I'm teaching this
    class like five years you think one of
    these days that actually poured in but
    there you go
    too much 35 there is 35 let's let's
    bring the dimensions in a little bit
    closer and okay what else are we missing
    we need to trim this bit of it away I
    click on the trim button I have power
    trim selected I just trimmed up a bit of
    it away and that's a fully defined
    sketch it has all the dimensions it
    needs and it's pretty good it has all
    the relations I want to show you
    something else though and let's say
    let's say I put in a dimension I don't
    know
    from that point that line to this point

    Watch video from 78:00 - 81:00

    and it's 25 and I'm going to just plot
    it there and I'm just going to go okay
    no that's that's what let's do that a
    bit slower I'm going to go from
    dimension from that line to that point
    and it says and this thing comes up you
    see all these yellow things coming up
    here what's happening here is you're
    adding too many dimensions it doesn't
    need us but why does it why doesn't it
    need it it already knows that the
    distance from that point back to the
    origin is 60 from that line to the
    origin is 35 so it knows that the
    distance from there to theirs it can
    compute it it's 25 so there's no need to
    add it so what you want to try and do is
    you don't want to over dimension your
    sketches now how do you know I'm over
    dimensioning it'll go red or will go
    yellow you'll see something like this I
    don't know okay so it'll go yellow or if
    I go from there to there it'll go yell
    it doesn't need us and you're over
    dimension in your sketch if you do
    something which a relation let's let's
    do this can i how can I do this and I'm
    trying to intentionally screw it it kind
    of tricky if you if you have relations
    that are going red or relations that are
    going yellow or if they're if you have
    red and yellow colors you want to delete
    them and you want to figure out why
    you're over dimension you have to think
    about it a little bit with with my
    experience like that that I just think
    the more sketches you draw it becomes
    instinctive you know so I I don't spend
    too much time I like to practice as many
    of them as possible and I think I think
    you finally gain the concept over and
    over to find ur a fully defined sketch
    so that's what one is that's sketch
    number six okay
    we've one more to go and it's sketch
    number seven and then you're done for
    the we would be done for the evening
    okay so I'll exit out here I'm not going
    to say that you can save yours if you
    want to and let's create a new part
    I changed the unit's right off the bus
    and I'm going to go sketch and I'm going
    to put it on the phone plan okay and we
    can draw whatever we want but let's go
    back and have a look so where where is
    it good point on this sketch to put the
    origin where do you want the origin to
    be my feeling is I just want to put it
    right here right at the bottom right
    hand corner okay and and then so what we
    want to do what's the plan of action it
    I don't know what this thing looks like
    it looks like some sort of an iron to be
    quite honest Gimbels you know an iron
    rod these little curves we're going to
    draw everything in and we're going to
    add in these fill its lusts so let's see
    if we can draw this thing I'm going to
    draw a line and let's just have a look
