GeometricObjects CATForeignPCurveData

Usage: you can derive this class.

public class CATForeignPCurveData

Base class of the attributes defining the data of a foreign Pcurve.

A foreign Pcurve is introduced into CGM by filling the CATIForeignPCurve object data with a CATForeignPCurveData. Then, it is automatically integrated into CGM, and can be used as any CATPCurve by the operators and the topology. To create your own curve type, you have to derive the CATForeignPCurveData class, and re-write the methods that are associated with.
