Description

You passed a three dimensional line variable to the routine L3_PL_INTER or LINE3D_INTER that is not in the normalized form.

Remedy

Make sure the line is normalized. Mathematically, this means that the direction vector must have a magnitude of 1.0 and that the reference point must have a zero component in the direction of the direction vector.
