Validates curve to be added to the view-specific shape being constructed. Called by AddCurve() to validate input. Expects a valid view normal to be set prior to the call.

Parameters
- GCurve
-  Type:  Autodesk.Revit.DB Curve  
 Curve object to be validated.
Return Value
True is %GCurve% is acceptable as a part of view-specific shape representation being built.Remarks
 This function may be used to pre-validate the geometry being added to avoid AddCurve() throwing an InvalidArgumentException Validation conditions depend on the type of view for which the shape representation is intended. For plan views, a curve is expected to be planar and non-degenerate (e.g., NOT a circle of zero radius).
