C++
double defaultStartWidth() const;
Description
Returns the default polyline segment starting width value for the polyline. This value is used as the default start width for all vertices within the polyline. So, for DXFOUT, vertices that have this start width will not write the value out. For DXFIN, vertices that do not have a DXF group code 40 value will use the polyline's default start width.
If non-zero, the default start width value is used for the polyline's DXF group code 40.
