If you have polygon feature
layers in your drawing, you can create new Polygon and MultiPolygon
features. MultiPolygon features behave like a single Polygon feature.
feature creation commands available for a feature layer depend on the
capabilities of the feature class represented by the layer. Feature
geometry follows OGC specifications.
A polygon has one outer
ring and can have one or more inner rings. A ring within a polygon
is considered a hole. To create polygons with multiple outer and
inner rings, create a MultiPolygon feature.
