public sealed class PointOnCurve3d : PointEntity3d

The PointOnCurve3d type exposes the following members.

Constructors
  Name Description
Public method PointOnCurve3d Default constructor for the PointOnCurve3d class. Creates a default corresponding C++ object with a point that does not lie on any curve and has a parameter value of 0.
Public method PointOnCurve3d(Curve3d, Double) Constructor for the PointOnCurve3d class. Creates a point on the specified curve with the provided parameter value.
