我想 应该是这个函数:
o CreateOutput
public virtual HRESULT CreateOutput( CATBaseUnknown* iGeom,
const IID& iid,
CATBaseUnknown** oOutput) = 0
Creates a 2D Output Geometry from 2D Geometry.
Parameters:
iGeom
[in] 2D Geometry of the current sketch.
iIID
[in] Interface identifier for which a pointer is requested.
oOutput
[out] Pointer to the created Output Geometry
