SS Button Assembly Drawing

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.

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.
