The Draw | Polygon Marker command creates a polygon marker. A polygon marker is a symbol, but has a special use for the Draw | Edit Boundaries | Create Polygons by Locator command. Didger stores an internal setting to differentiate a polygon marker from a normal symbol. If you draw a polygon marker in the middle of some snapped polyline segments, you can use the Create Polygons by Locator command to generate a polygon from the polylines.
