Type Documentation

enum A3DEIntersectionLimitType

Intersection limit type.

Version

2.0

Values:

enumerator kA3DIntersectionLimitTypeHelp

Arbitary limit on a closed intersection curve.

enumerator kA3DIntersectionLimitTypeTerminator

Limit where one of the two intersection surface normals is degenerate or where they become colinear.

enumerator kA3DIntersectionLimitTypeLimit

Artificial limit to avoid an infinite curve.

enumerator kA3DIntersectionLimitTypeBoundary

Limit of the curve if a A3DSurfBlend02 surface (that uses the intersection curve as its center curve) becomes degenerate.
