Michael,

As the BRep surfaces are made with a point structure - performing Boolean operations on them produces new shapes by assigning clips or masks to represent cuts in the surface.

In much the way ShrinkTrimmedSrf is a method to reduce a point structure by removing unused surface elements,

Maybe by removing the trimming mask assignments - I see that the point structure is still there and intact on any given surface object, surely its original whole self can be reclaimed.

Is there a command or script for "restoring" the original BRep surface to its original whole shape?
I could swear I've seen something like this before...
