PK_ICURVE_t    




This type represents an Intersection CURVE.  An intersection curve is a
connected subset of the intersection between two surfaces.


An intersection curve is a type of curve (PK_CLASS_icurve is a subclass of
PK_CLASS_curve).

An intersection curve has no standard form.  Intersection curves are created
when surfaces are intersected and the intersection cannot be represented by
one of the analytic curves.
