- [Instructor] There are many different techniques
in which you could use
to generate the actual part thickness.
This method is called the shell method.
Here I have a final solid volume.
Now the shell method allows me to take a tool
called shell and specify the face
that I want to remove on the part.
So in this case it's this back face.
And then I can enter in a value.
Since I have a part thickness for a parameter,
I can use that for my value.
You'll notice there's an inside and an outside thickness.
So if I come over here, hit equal, enter on the keyboard,
specify my thickness and select okay,
you'll see I have the actual part thickness.
And it's computed by a shell.
An alternative method to this shell
is to use another tool called thickness
where I don't necessarily use a closed surface,
I just take the final surfaces and just apply a thickness
to the surfaces and I'll end up
with a sort of similar result to what I have with the shell.
Both of them lend themselves well to a certain type of part.
Maybe you're building something very large and complex.
That would require additional slides
and further greater than just a simple core cavity design
and that's where you may use the shell method
or you may use the thickness method
versus a core cavity design method.
Now, how you get the thickness
is going to be similar as far as having a parameter
where I can now go in there if I need to make a change
to the thickness.
If I double-click on that and say let's say that's four,
you'll see the parameter drives the corner radius thickness
and everything updates.
Those kinds of techniques are going to be similar
from one to the other, but how you get the final thickness
is a bit different.
So, with the shell you simply pick the face
that you want to remove.
You double click on that and give it an inside thickness.
You'll notice that I also have an outside thickness.
Outside thickness is very useful
when you're designing based off of a specific
or a required volume.
So maybe you want to have a bottle or container
that holds a gallon of fluid.
Let's say like wiper fluid and you want a design
based off of your environment,
because it's not just a bottle
it's going to have cutouts and scallops.
Then once you design the volume,
you can give it an outside thickness.
So that outside thickness can now contain
that appropriate amount of volumes.
So this shell definition, the shell tool, great tool
and again depending upon what you're doing,
go ahead and use it.
