- [Instructor] Within the CATIA tool set,
we have various manners in which we can create surfaces.
CATIA's an extremely powerful tool
and it affords us all sorts of ways
surfaces can be generated.
I'm going to go under the Start pull down
and this is where we can see
all of our workbenches.
Here you can see Generative Shape Design,
Freestyle, Quick Surface Reconstruction.
These are here based off of the licenses that I have.
Generative Shape Design
which is what we're going to be talking about today
is a workbench for parametrically generating surfaces.
This can create pretty much any shape that you want
and for most engineers
they're going to be using Generative Shape Design
and the reason behind that is because you can do
mechanical surfaces, you can do some styling
parametrically based as well
and it actually has some very powerful analysis tools
for surfaces which we will be talking about some.
When we go into Freestyle,
Freestyle is more of the NURBS modeling.
You'll see exteriors of cars,
interiors of automobiles, airplanes,
in some cases they will use some very freeform shapes
and this is where we go in and create those freeform shapes.
We won't be talking about that
in this course today
'cause again, it's a completely different discipline
and Quick Surface Reconstruction
is another workbench that allows us
to create surfaces based off of STL data,
so if you have something that you have scanned in
or maybe somebody's modeled up
a model in a clay and they've scanned that in
and you want to quickly throw surfaces
over the top of that,
again, this is for highly stylized surfaces
which may be very difficult
to visualize without having an initial 3D sculpture
sitting in front of you
that you can take a look at
and see how highlight lines flow
or light splashes across the surface,
so again, today we're going to be talking heavily
about the Generative Shape Design.
I just wanted to mention the other workbenches
because I know a lot of you are going to go back
and you're going to have questions
about what are these other tools for,
so the Freestyle and Quick Surface Reconstruction
are more for the highly stylized type of surface.
