Brep to BrepFace or Brep/BrepFace to Surface

This is probably easy for seasoned scripters, but for a noob like me it's a 10+ hour adventure.

I am attempting to write a vb.net component which will do a variety of things with breps.

I've had some success in the past with writing the code, but I am constantly getting hung-up on a couple of points. The first are the Classes (I guess that's what they are called.)

I have a couple of different classes. The two or three I am focusing on are:

Brep

BrepFaces

and

Surface

What's so troublesome is trying to convert the member of one class to another.

What I really want to do:

Convert a Brep.Faces.ExtractFaces(1) to a Surface so I can get the centroid.

And

Convert a list of Brep.Faces.ExtractFaces to a BrepFace

I am so lost.

You can access BrepFaces via the Faces property of a Brep instance:

Dim B as Brep = 'somebreporother

Dim F As BrepFace = B.Faces(0)

BrepFace has a DuplicateFace() method that creates a new Brep that looks just like that one face. You'll probably need this if you want to find areas and centroids of trimmed faces.
