Adds two or more polygons together and eliminates the overlapping edges.
Point 1: First Polygon
Point 2: Polygon to be added to first
The polygons are combined into a single polygon, and the boundaries “internal” to the resulting polygon are removed.
NOTE: For best results, the polygons should overlap, rather than meet exactly at an edge or point.
To combine more than two polygons, select the polygons first and then select the Polygon Add command. Click Use Selected
NOTE: Regardless of which alignment was used when creating the double line, DesignCAD has to use these points to create a center-aligned wide line. This can cause the appearance of the resulting wide line to vary slightly from the original double line.
