Syntax 
public sealed class ExternalCurve2d : Curve2d

The ExternalCurve2d type exposes the following members.

Constructors
  Name Description
Public method ExternalCurve2d Default constructor for the ExternalCurve2d class. Creates a default corresponding C++ object with a pointer to the curve definition set to NULL, undefined entity for a curve type (no information about the system that created an external curve in other words) and an option to prevent creating a copy of the external curve.
Public method ExternalCurve2d(IntPtr, ExternalEntityKind) Constructor for the ExternalCurve2d class. Creates an object with the specified pointer to an external curve definition and the specified kind of curve.

Remarks
OdGeExternalCurve2d instances can be treated as any other OdGeCurve2d. You can access the OdGeExternalCurve2d as a corresponding native OdGeCurve2d, if such a corresponding curve exists, or you may (more efficiently) access the external data in its native form. One example of using OdGeExternalCurve2d is to access an ACIS curve.
