object Evaluate(

Object^ Evaluate( 
&   double Parameter
) 

Parameters

Parameter

Value of the edge parameter

Return Value

Array values containing the x,y,z value and derivative of the edge (see Remarks)

Use IEdge::GetCurveParams2 or IEdge::IGetCurveParams2 to determine the valid parameter range for this method.

This OLE implementation of this method returns an array of doubles as follows:

[ PointX, PointY, PointZ, TangentX, TangentY, TangentZ, Success ]

where the point values are in meters and Success is True if successful and false if not.

The return value for the COM implementation is different. To determine success, check the HRESULT return value. The array is as follows:

[ PointX, PointY, PointZ, TangentX, TangentY, TangentZ ]

where the point values are specified in meters.
