Parameters

Parameter

Curve parameter

Return Value

Pointer to an array of doubles (see Remarks)

To determine a valid parameter range, use ICurve::GetEndParams or IEdge::GetCurveParams2 or IEdge::IGetCurveParams2.

The OLE Automation return value is an array of doubles with the following format:

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

where:

• PointX, PointY, and PointZ represent the 3D point in space for the given parameter

• TangentX, TangentY, and TangentZ represent the tangent vector at the point

• True if the operation is successful

The COM return value is an array of 6 doubles representing the point and tangent. The success value is determined from the HRESULT return.

This method returns values in meters.
