Use this command to convert an existing closed polyline to a polygon.
Respond to the prompts:
Select the polylines to convert. Press Enter.
Each closed polyline in the selection set is converted into a polygon. If the polyline belongs to a group, only the first (outermost) polyline in the group is converted. Other polylines in the group are copied into the polygon as additional boundaries. The polygon is automatically rebalanced.
When objects are converted to polygons, they use the default color or hatch set by the MPFILL command.
