Boolean getTreatClosedPolylinesAsPolygons()

Specifies whether or not polygon layers that are created from DWG data treat 
closed polylines as polygons. A value of True indicates that closed polylines 
are treated as polygons. A value of False indicates that closed polylines are 
treated as individual polylines, not as polygons. 

Note  If this method is set to False, and closed polylines are treated as polylines 
instead of polygons, the polylines are displayed on a polyline layer instead of the 
polygon layer.

For more information about how closed polylines are treated on polygon 
layers that are created from DWG sources, see Chapter ? on page ?.
