- The Replace Face command is very much like an
Extrude Up to Surface however if you already have a
existing solid body and you want to replace one of the faces
that is where the Replace Face command comes into play.
So what I have here is I've got a rectangular block
on the bottom here and I've just created
an extruded surface directly above it.
Keep in mind that that surface completely covers
the block below it.
Go ahead, go up to Surfaces and Replace Face.
And right here I'm going to choose
the tangent faces for replacement,
and that's going to be this one right here.
And then I'm going to choose which surface
I want to replace that with.
Click on that one there and click Ok.
And just that easily I have removed that top surface
and extended it all the way up
to this existing surface here.
Then I can go back and take this surface body here
and just hide it, and there's my resulting solid.
So a very simple and easy command
but very helpful if you need to replace a face
or just kind of extend something up to a surface
without going back and changing the way that surface
or that extrude originally was created.
