primdist expression function

Returns the minimum distance and closest points between two primitives.

See also: pointdist, xyzdist, nearpoint

• return_type = 0: minimum distance

• return_type = 1: U value of closest point on primitive 1

• return_type = 2: V value of closest point on primitive 1

• return_type = 3: U value of closest point on primitive 2

• return_type = 4: V value of closest point on primitive 2

Only works for faces, curves, and spline surfaces. Other types of primitives will always return 0.
