Modeling holes in a Sub-D mesh.

Lightwave 3D technique for creating holes in a curved sub-division surface.

The idea is based on a Modo tutorial by Richard Yot and makes use of the recent Lightwave tool - Heat Shrink. The video begins using the technique to create a hole in a flat surface. There are plenty of other great methods (check out William Vaughan's site) for creating holes in a flat surface, but I figured it wouldn't hurt to see the technique used in different scenarios.
