SMS:Build Polygons

While most feature objects can be constructed with tools in the Tool Palette, polygons are constructed with the Build Polygons feature object 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. All closed loops will be formed into polygons. Before defining material zones or creating meshes from a coverage, the Build Polygons command must be used first.

Polygon Attributes

The Polygon Attributes dialog is used to set the attributes for feature polygons. Attributes that can be specified for each polygon include:

• Polygon Type – The polygon type can be set to either Land or Ocean.

For models that generate meshes, there are certain polygon attributes that need to be set before the mesh can be created. For more information, see 2D Mesh Polygon Properties.
