- [Instructor] Here I'm going to talk about fill surface.
You can either use the file downloaded,
or you can go in and select the fill function,
hit F1 on the keyboard,
download the file from your CATIA install documents,
and open it up.
Let's get to work.
Under the fill function,
you have outer boundaries and inner boundaries.
We're going to start out with outer.
For the outer boundaries you can pick as many elements
as you want, curves, surface edges, whatever it may be
to form a single closed contour.
In this case I have one curve.
I picked that one curve.
With that, simply picking it, closes out the contour.
I hit my preview and there's my closed off surface.
If I had two, or three, or four, or ten curves,
just pick those in order and in a chain,
and you have your fill surface.
I also have the ability to specify inner boundaries.
I'm going to come in, pick a new inner boundary, preview.
That's my first inner boundary.
If I wanted an additional inner boundary, as you see here,
I come in, say, "Add new boundary."
Pick the new closed contour.
Again, these can have as many segments in them as necessary,
as long as its a closed boundary.
Preview, and there's my fill.
I'm just going to cancel that.
I'm going to go back in fill.
This time I'm going to pick my outside boundary.
I also have the ability to pick passing elements.
In this case, I'm going to pick one of these points.
Preview, as you can see,
that fill goes to the closed off boundary
and is now passing through that point.
I can pick another point here.
Now it's passing through both of those points.
Or, if I want a third element,
I'll go ahead and cancel that out, go back into fill,
pick my outer boundary, and in this case,
I want to come in for my passing element,
pick this curve.
As you can see, I have a closed off boundary.
Now it's passing through that curve.
Fill's a very powerful surface operator.
You have to be really careful with it,
as you go through and do use it,
because it can create
some really crazy surfaces, wild undulations.
Just be cautious when you're using fill
for anything other than a planer surface.
Planer surfaces, it's great.
For anything else, verify that the surface looks good.
Make sure that whatever you're using it on,
it doesn't create some crazy shapes,
because as a single surfacing function,
or surface generating function,
it will do some pretty amazing things.
Again, you can pick as many curves
as you want for a boundary,
so long as they form a closed profile.
You can pick these passing elements,
and because of that, again,
it can create some crazy shapes,
things that can't necessarily be made.
Just go careful when you use it.
Great tool.
Observe, verify, make sure everything's good.
