Shrink Trimmed Surface

The ShrinkTrimmedSrf command contracts the underlying untrimmed surface close to trimming boundaries.

Shrinking a surface is like extending smoothly, only backwards. knot of full multiplicity are added where you want the surface to be cut off. Then the remaining control points are thrown away.

The ShrinkTrimmedSrfToEdge command contracts the underlying untrimmed surface right to the to the trimming boundaries.

Shrinking the trimmed surface can sometimes cause problems later since having the edges so close to the trimming boundaries can cause commands that use the surface edges as input to fail.

Compare the video with ShrinkTrimmedSrf. Notice in the close-ups that there is a tiny margin between the control points and the trimmed surface. This margin is eliminated with ShrinkTrimmedSrfToEdge.
