C++
Adesk::Boolean isMClosed() const;
Description
Returns Adesk::kTrue if the PolygonMesh is closed in the M direction, or Adesk::kFalse if the PolygonMesh is open in the M direction.
A mesh closed in the M direction is treated as continuous from the last row on to the first row.
The M closed status is reflected in bit 1 of DXF group code 70 (that is, if bit 1 is set, then the PolygonMesh is closed in the M direction).
