Divide Surface Along Creases

The DivideAlongCreases command creates a polysurface by dividing a surface into separate parts at kinks or tangents.

Creased surfaces are divided into smooth pieces joined in a polysurface. Creased surfaces within a polysurface are divided and joined within that polysurface.

Command-line options

SplitAtTangents: Divides surfaces at tangent locations.

SplitAtKinks: Divides surfaces at kinks
