Adesk::Int16 mSize() const;
Description
Returns the vertex count in the M direction. This is the number of vertices that will be used to make up an M row in the PolygonMesh if the PolyMeshType is AcDb::kSimpleMesh. For any other PolyMeshType, the M surface density value will be used as the row size.
The M size value is used for DXF group code 71.
