Adesk::Int16 nSurfaceDensity() const;
Description
Returns the surface density in the N direction. The N surface density is the number of vertices in the N direction after a surface fit operation is performed. This value is used in place of the N size value if the PolyMeshType is anything other than AcDb::kSimpleMesh.
The N surface density value is used for DXF group code 74.
