Generates a polygon footprint for the object in an arbitrary plane. The footprint may have multiple parts.
[Visual Basic .NET] Public Function ProjectToPlane ( _ ByVal planarOrigin As IPoint, _ ByVal planarPositiveX As IVector3D, _ ByVal planarNorm As IVector3D _ ) As IGeometry
[C#] public IGeometry ProjectToPlane ( IPoint planarOrigin, IVector3D planarPositiveX, IVector3D planarNorm );
[C++]
HRESULT ProjectToPlane(
IPoint* planarOrigin,
IVector3D* planarPositiveX,
IVector3D* planarNorm,
IGeometry** footprint
);
[C++]
Parameters planarOrigin
planarOrigin is a parameter of type IPoint planarPositiveX
planarPositiveX is a parameter of type IVector3D planarNorm
planarNorm is a parameter of type IVector3D footprint [out, retval]
footprint is a parameter of type IGeometry
