SMS:Build Polygons (Feature Objects Menu)
From XMS Wiki - http://wikis.aquaveo.com/xms/
While most feature objects can be constructed with tools in the Tool Palette, polygons are constructed with the Build Polygons command. Since polygons are defined by arcs, the first step in constructing a polygon is to create the arcs forming the boundary of the polygon. After forming loops with arcs, choose "Feature Objects | Build Polygons" from the menu.
The build polygons command will form polygons from all closed loops in the coverage.
