- [Instructor] The frame modeling is now finished.
Although, depending on your own requirements,
you might have added more details
than my assembly here.
At this stage, we can also add some off-the-shelf components
into the model to make it look more finished
but also to check that everything works as expected.
These are parts like the seat post and the seat,
the wheels, the crankset,
so the pedals and the bottom bracket,
and of course the fork and handlebars.
If you're starting fresh at this point
and using the exercise files,
then unzip the chapter five files to a new folder
and open the assembly file for chapter five.
For the new parts that we're going to add,
I've provided some simplified models that you can use,
and these can be found under the chapter five files.
You can also model up parts yourself
from manufacturer's drawings and specifications,
or you can search online
for existing models that you can use.
We'll start with the rear wheel,
and these files are provided in a STEP format.
This is a common file format that can be opened
by many different CAD programs,
and it just allows anyone watching to use these files
even if they don't have the same SOLIDWORKS version as me.
So if you're running an older version of SOLIDWORKS,
then you should still be able to open these STEP files
and use them in the frame that you've modeled yourself.
Download the STEP files,
and to use them, open your existing assembly in SOLIDWORKS,
and then just drag the file into the assembly.
So let's start with the rear wheel assembly.
So just drag the file into SOLIDWORKS
and you should see an import box like this.
Depending on the speed of your computer,
it might take a moment to import, but when it does,
it should come up with something sort of like this.
We can then fix this in place using some mates.
So I'm going to zoom in,
I'm going to select that circular edge inside the hub,
and then I'm also going to select the circular edge
on the axle here,
and I'm going to add a concentric mate.
And you see the rear wheel moves into position.
If we look at it, the cassette's actually on the wrong side,
it should be on the right-hand side.
So you might not need to fix this in your model,
but if you do, you can go all the way
to the bottom on the left,
expand the Mates folder,
find that latest concentric mate,
should be at the bottom,
right-click on it and press Flip Mate Alignment.
And then it should spin your wheel around like so.
Then we can line the wheel up left-to-right.
So I'm going to expand that rear wheel assembly.
I'm going to select the right plane,
and I'm also going to select the right plane
of the assembly,
and I'm going to add a coincident mate.
So that's moved into the correct position.
And now we can actually spin the wheel around
and see how it looks.
If we look from the top and look around this area,
we can see there seems to be plenty of clearance
around here for the wheel and the tire.
But if there wasn't, we could maybe adjust these parts,
the chain stay or the seat stay,
and give them a bit more clearance there.
Now we can add the crankset in the same way.
So find the file,
It should be called Crank and BB Assembly.
Just drag that into your open assembly.
And again, it will start to import like this.
Once it's imported, we can also mate this in place.
So I'm going to select that circular edge,
and also select a circular face down here
and mate those concentric.
And again, we've got this back-to-front,
so this sprocket should be on the right-hand side.
So to fix this again,
we can find that latest concentric mate,
and then just right-click on it
and press Flip Mate Alignment,
and that should spin it around to the correct side.
And now if we look at the left-right alignment,
this is a bit of a simplified model
but basically, this inside face
of the bottom bracket there
should be coincident with the outside of the shell there.
So select that face, hold down Control,
also select that face on the shell,
and then let's add a coincident mate,
and that should move it into the correct position.
So now, if we look from the top,
we can see the sprocket is clear of the frame there.
On this side, the pedal's clear,
maybe it's a little bit too close.
So if we find that's a problem,
we could always adjust the line of this chain stay,
and maybe move the tube in a little bit.
But I think for now that looks fine,
so we can save the assembly,
and in the next video,
we'll continue on by adding the seat assembly
and the front fork.
