In this video, I'm gonna make a quick demonstration
on how to create an assembly drawing in Onshape.
We're gonna use a very simple part,
which is the start/select button for the NES
game controller by Nintendo.
And
we're going to
just going to show you how it's done.
OK.
All right.
So,
looking now into Onshape,
you can see that I am looking at an assembly drawing of the entire controller.
And I just want to point out the kinds of things that exist
in assembly drawings so that we can try to create them
when we make our own
drawing of the
start select
button
assembly,
right?
So, we will often have an exploded view with a bill of materials
in
an
assembly drawing. And here, we see that's on
sheet 2 that's where that typically would show up.
And then, here on sheet 1,
we have the orthographic projections with an Iso view with any important notes
and then some assembly dimensions.
That's all we're gonna try to do
in this simple example.
So, I'm gonna show you how that's done.
I am working in my NES folder.
I should call it NES document.
In my NES documents, I have three or four,
excuse me,
special folders.
All my assembly studios are here.
All my part studios are here.
My drawings are here, and my decals are over here.
We're going to create a new drawing.
And we're going to
simply
hit the plus button and create a new drawing—
create drawing.
We want to create a drawing using this B size format.
So, we're going to pull that in.
OK.
Then, it's gonna ask us what part we want to do or what assembly we want to do.
And we want to do an assembly of
the
subassembly of the SS button. That's what we want. So, bringing that in,
it's now gonna give us our orthographic
projections that's our front view.
Here's our top view.
Now, I'm already on projection. So, I can get this view.
And
let's get our bottom view in there because we will probably need it.
Also,
what we're gonna do on this is
switch our scale from 3 to 1 to something smaller.
OK.
3 to 1 to something smaller.
So,
how am I gonna do that?
I'm gonna
just escape out of what I was doing there and right click
on this and get to our sheet properties and just switch this to
2 to 1.
OK.
Everything gets just a little bit smaller that way.
I can move some of these things
off in these other directions.
So, this is what our sheet 1 is gonna look like.
We're gonna have
an Iso view in there. So, let's go get an Iso view front—
Iso.
OK.
Gonna pop our eyes of you just like that.
OK.
And
it's
probably gonna be helpful to see the underside of this.
So, one way that we can do that is we can just do a projection
off of that.
We can grab this guy and just project
below it, and now we can see
those parts are there.
We can see that it's an assembly of a couple of things.
All right.
Now, we have some title block work that we're gonna do,
but
we also have to think about the exploded view
that we need to get in here.
So,
let's just go change some of the metadata on this drawing starting with
its name.
OK.
So, this is going to be my SA S slash S, that's the subassembly for the SS button.
OK.
The
title of my drawing is going to be
sub-assembly.
Sub-assembly. Let me put a dash in
there.
Sub-assembly.
Start
slash select
button.
OK.
The person who drew this
is me.
CA Matson.
The day that it was drawn was this 9th
of August.
Selecting that. It has not been checked yet,
so that's not gonna get anything.
My revision,
I'm gonna put a revision 1 since I'm not imagining it to be released yet.
OK.
I can actually
leave
this like this because
it's not,
I'm not actually releasing it yet.
OK.
Revision is released.
OK.
Finished.
I don't know.
OK.
Comments:
See
Part Drawings.
Oops!
This is what we should say for the finish is "See
Part Drawings."
OK.
Comments.
I don't need to have anything in there.
I could put those dashes back in there.
OK.
Our part number doesn't matter for the drawing.
We're actually gonna get the part number from the subassembly,
apply, turns out the subassembly
part number is already there.
I can see it down here because it was in the metadata for the subassembly.
I can also see that millimeter is in there.
That's from the metadata of the subassembly.
And so, we've got our title block settled.
That's everything we need in there.
Now, what we need to do is let's get our second sheet in.
OK.
So, come over here, and we create a second sheet,
add a sheet.
OK.
And now, in this sheet, I'm seeing my revision block up here which I don't want.
So, I'm just going to look at the properties of that sheet
and change this
into
the continuation,
which is this one.
You can learn about that in the
video that describes how to create a part drawing.
Now my revision block has gone away,
but I still have all the other things in here that are needed.
And what we want to put into this one is the view
that is the Iso view.
OK.
Hold on a second.
View orientation,
isometric.
We
actually haven't made an exploded view for this yet.
So, we need to actually go into our part studio
and do
that
quickly.
It's actually in our assembly studio.
We're gonna do that right now.
OK.
And what we're gonna do is we're gonna look at
this from the upside down view because it's gonna be more meaningful
if we have an exploded view that's basically like this orientation.
OK.
So, I'm gonna save this as a named view,
and I'm gonna call this Iso Explode because that's what I
like to call the ones that are related to that.
OK.
Then, I'm gonna come down here and make the exploded view and add an exploded view.
Luckily, it's so easy.
I only have two parts I need to pick,
and those are my parts right there,
and that's about the extent of my exploded view.
Unexploded and,
that's not what I wanted.
Unexploded and
exploded.
OK.
So, that's that. We've got that.
And
I think that I am just for
fun
going to unexplode this for a second.
OK.
Let's see.
What I was thinking about is I want
to have this orientation unexploded and exploded,
but I already saved this one as
Iso Explode,
right?
So, we should be able to go into our drawing set at this point,
into the subassembly for the SS button.
And I'm on my second sheet.
I can now insert some views,
and the view that I want to insert is
my Iso Explode.
OK.
There's the
exploded or the Iso view.
I can right click on this then and get the explode state.
OK.
I can see what's going on up here.
I need to refresh my part,
just this one.
And now, I can right click on this,
and I can come over here to my display
state, explode state, and go to my explode one state.
And I got this.
This is actually working out just the way I want it to
because what we want to do is add a bill of materials to this now.
The way we're gonna add the bill of materials is we're gonna come right up here to
not this one, which is table, but the one right next to it, which is BOM
table,
which means bill of materials table.
I'm just gonna click it in anywhere right now.
And what's interesting on this is
that
I
don't have any
awesome
metadata coming in the way I hoped we would have metadata coming in.
Why do we not have any metadata coming in?
We must not have done anything with our part
for the pill,
and we haven't added in a description
for this part.
So, we're gonna have to fix that right now.
So, we're gonna come in here and first of all just
take this guy and move it right down here to this corner.
Then, we're going to stretch this out and
stretch this guy out.
We don't need our item one to be so big.
That one's kind of dumb if it's too big because there's nothing in there except that.
OK.
And
I'm just trying to line it up with this edge right over here.
OK.
This is our bill of materials,
but when we made our parts, we weren't
careful enough to put part numbers in or descriptions.
So, we're going to go take care of that right now by going over to,
first of all, we need to go get the right numbers for what these are.
Let's go into our assembly studio and into the NES controller
and onto the second page to see these this bill of materials
to get what we need.
So, first of all, we're working on SS.
OK.
So, that's the start select button.
So, we're looking at
subassembly 4.
And we need the membrane, which is 402 or 4002 NES.
And that's
the membrane.
And then the one underneath, it was the pill,
and that's 4004
GEN.
And we're gonna go into our part studios
because that's where the metadata is stored for this.
And we're gonna go into our SS button, and we're gonna look at properties,
and we're going to open up the part studio and look at the SS button
and see that
I do have a part number there. So, that's good.
Why it's not showing up and the other thing? That's
we're gonna have to figure that one out in just
a little bit. But we can add our description in here
which is the
SS Start
Select
Membrane.
OK.
There's our part, project, NES, silicone rubber, millimeter.
OK.
We're gonna apply that.
OK.
Then, we're gonna look at our contact pill,
which does not have a part number
4004-GEN.
The description on this one is
contact
pill,
3 millimeters.
And this is for
Project NES.
On this one, and then unit of measure, we're gonna go up to millimeter.
We should have done this before,
got our metadata sort of just all cleaned up.
And let's go see if this has solved any of our problems.
It may not have solved all of them,
but we're gonna see if it has.
InTO our drawings,
into our subassembly SS button,
hit the refresh button over here. We should at least see descriptions pop up
good, and we see both of our part numbers pop up.
So, that has worked out really nicely.
This is all that needs to appear
in the second page.
It is our exploded view.
Actually, we need to fix one thing in a second.
This is our exploded view, and this is the bill of materials.
Now, what's missing is we haven't said what is item 1 and what is item 2.
And the way that we do that is we use the balloons, and this is the balloon call out
right here.
OK.
Is this right?
OK.
Yep.
And what we're gonna do is we're going to pick on this part,
and go like this,
and that's gonna say that that's part 2.
And we're gonna click on this part right here, and it's gonna say that that's part 1.
I like to line up these lines, so they're parallel
to each other.
I think it looks cleaner.
So,
that's that.
Let me hit escape to get out of the callout thing.
And let me pull number 2 in
so it's not so far away.
OK.
Pull number one in a little bit, so it's not so far away.
Now, one of these is a dot and one of these is an arrow.
What is the difference here?
Anytime it's produced,
anytime it's pointing to an actual piece of geometry such as the center,
it's going to do an arrow.
If I do the edge,
it'll do the same thing,
but if I go just right to the middle,
it will create a dot.
I think the dot looks a little bit
cleaner
because it's,
I
think, a little bit easier to identify
where it is.
So, what we've just done is we created part page 2
of this assembly drawing,
this very simple assembly drawing,
and it is done.
So, that's great.
What we need to do is go back over here to item number 1,
excuse me,
page number 1,
to do a few important things that need to be put in
here.
First of all,
assembly drawings never have
hidden views,
hidden lines shown.
So, we don't need to add any hidden lines
or make any comments about them not being there.
But what we do want to do is put the overall dimensions on this
and then put in the assembly dimensions.
And I can see
that there is
a few assembly dimensions that we should be thinking about.
OK.
And
let's just get some key dimensions on here first.
So, I'm gonna hit D.
I'm gonna go from this line over to this line.
It's gonna give us our overall width.
OK.
Then, I'm gonna go from this line up to
this line right there and that's gonna give us our overall height.
And then,
I'm going to get this line to this line to get us our overall width.
OK.
There's our overall width.
Yeah.
I like to think of the length is the highest.
You know,
the largest number,
the width is the second largest number,
and then the height
or the thickness
is the smaller number.
OK.
So, that's those key dimensions.
Now,
we
do have two parts that are assembled to this.
OK.
They're assembled to this,
and we need to know the center to center distance between those.
OK.
And it could be helpful to know where are these in space.
OK.
So, let's go ahead and put in a center line
from say
here
to here.
This is not what I want it to do.
OK.
Let's undo that—control Z.
Actually, just grab it and hit delete.
I want to get this edge-to-edge center.
So, I want to like pick yes.
This is what I was trying to do before in something
odd happened there.
So this,
if I pull it all the way down below my part
and to all the way above my part will represent the
center line of this object, which will say that it's symmetrical
across from this.
Now, what I can do is add a center mark onto
one of these guys,
all right,
like that.
Oops,
I have escaped out of that,
so back to our center mark.
I have...
I
want to accept that
And now I can do...
I might as well put a center mark in this other one right here.
OK.
Since we're dimensioning to it with the 16.
Now, what I can do is dimension
from
this center
over to the center line,
and then we can know now that that's placed that way.
What we haven't done is said that it's centered in this
other direction, which we can do in a slightly simpler way
by putting in our center lines from here to here.
OK.
And escaping out of that and then just pulling this all the way this way
and all the way this way, and then visually
it can be seen
that those share the center.
So, that is to find the assembly of that
with one exception.
We actually need a cross-section, and our cross-section
has to show what's going on with that contact pill.
All right. So,
I'm gonna come up here
into this area.
And because I want to get a cross-section right through one of those pills,
I'm
gonna put a center mark on that.
OK.
Then, I'm going to get a cross-section marker,
which is going to be vertical.
I'm gonna click on that center mark,
and then
I can just look wherever I want like over here, for example.
OK.
Now,
let's take this section,
pull it down here.
Oops!
It's not what I wanted to do because I have not delinked them yet,
so to speak.
I have not suppressed the relationship that says they have to be
next to each other. So, suppressing the alignment with the parent.
I'm gonna bring this down here,
and I'm going to
change the size of this so it can be
seen.
Actually, I'm not gonna do that.
What I'm gonna do is
leave this right here
and now make a detailed view
of the one thing that I have to measure
just like right in here. So, we'll go straight from that center, and I just need
that information.
I need that information right there.
OK.
That's good except we wanna make this now as big
as we can possibly make it because we need to
dimension to it.
We don't wanna move the name; we wanna actually move the view.
So, double clicking on this.
I'm gonna switch this to a
like a 16 to 1.
OK.
That's pretty giant.
Let's see how messy this looks on our drawing.
OK.
It's not horrible.
What we're gonna do is
move this guy over here just a little bit,
move this guy down just a little bit
right here,
trying to just tune this up,
make it look good,
this one up just a little bit.
Move our section view over just a little bit,
and then give this guy a little bit of breathing room, and
that's looking good.
OK.
What we need to do.
OK.
This is our contact pill.
OK.
And the reason why it doesn't look like a cross-section is because I
didn't take my cross-section through the pill, which is right in the middle.
That probably would have been
useful
to do.
And
so, let's dimension this though, nevertheless.
I'm gonna go and dimension
from here
to here. This little point
is a very critical number for us.
I'm gonna pull it out right over there,
and I'm gonna
say typical on this because it's gonna exist in
various places on this. I need a space first,
typical.
OK.
Now, I need to adjust this so
that
it doesn't look so bad.
Don't want to really have all these lines crossing.
But I don't have a lot of options.
So, I'm just gonna have to pull it out here like that.
OK.
Now, let's see if we can fix this detail. Let's see if we can fix this section view.
I don't want this section view to go through that.
I want it to go through something that's more like that,
but I'm going to have to delete that relationship.
How am I going to do that?
Flip,
paste,
delete.
I
don't wanna delete the section.
That's going to mess that up.
OK.
Can I delete my center mark?
Where is my center mark?
Is it on here?
OK.
Isometric top view,
detail view,
section view.
I
am not entirely sure how to do that,
but I could just take this and go give it to some other entity
like that.
OK.
And that helps us.
I had to break it away from that one.
Now, I can take this over here,
oops,
take it.
Take it away from this, and we need to go
right up into that part there.
OK.
Now, what have we seen?
We see a little bit of trouble in here. It's turned red because it's a little bit
confused about where the center point of this is.
OK.
But all we have to do is grab it and reapply it.
And it will,
and that will work.
So, what we have just done
is we made
this
so we could see the cross-section of the pill.
Now, this dimension has lost its reference because we
moved it. Now, we can just put it back,
and we can move this reference and put it back,
and we'll be all sort of settled there.
OK.
So,
that is that. We created
a drawing
that has an assembly in it,
and it's a subassembly drawing because it's part of a larger thing,
the NES controller.
We have also
had a second page. And in our second page, we have our exploded view, which
is very simple in this case, and our bill of materials which is linked to the
metadata for the part.
We have our title block, which is linked to both
the metadata of the part and for the drawing.
And by part, it's actually going to the part and the subassembly metadata and
the drawing
metadata.
And
we have a reasonable drawing here where we
have the overall dimensions shown in the orthographic projections.
We also have assembly dimensions,
things that don't exist on part drawings but only exist in
assembly
drawings such as the center to center distance on this,
which is 16.
Now, we have two things that we need to take
care of before we are totally done with this video,
and one of them is that we want to make sure that we create a version of this.
And our version of this needs to be a V1 because we haven't released yet.
OK.
And this is saying we need to update this before creating a version,
but I'm gonna get a name on here.
This is going to be the
subassembly SS
button
drawing.
OK.
And I'm just gonna do this before we make
that
version.
And we're gonna save it, and that's now saved.
But
what do we do if we want to actually get it out of this CAD system?
Well,
we need to right click down here and hit export,
and we want to export this as a PDF, which we're going to do.
Now, you might be imagining that this is going to
be exported to a computer somewhere or something like that,
but it's actually just exported
to your actual NES document.
OK.
It's right here.
SA S-S dash button
PDF.
Here is the PDF that we just created.
Now, if you want to have this
SA S-S button PDF on your computer,
you right click on it and you download it, and it goes into your downloads,
and then you are all settled
for
being able to share that drawing with someone else
who's not in Onshape
or sharing it with a vendor or putting it in a portfolio or
turning it in for a course assignment or anything like that.
OK.
What do we do in this video?
Well,
we created an engineering drawing.
We learned how to create an engineering drawing.
There are a number of simple things we needed to do to get the
metadata linking together,
and there's a few things we needed to do to get
the views in place,
and a few features that we haven't really thought about before
at all,
which is how do we get the bill of materials table in there
and how do we get the balloons
and how do we choose
view orientations
that make sense and how do we turn on the exploded views.
Those are all the kinds of things we did in this video,
which go into part 5 of the good CAD process, which is ways that we present
our modeling work,
our engineering work
to other people.
And an engineering assembly drawing is a fundamental way to do that.
