You can change the location of an AEC polygon, adjust the width and justification of its edges, and change how it is displayed in your drawing. You can also redefine the geometry of an AEC polygon or define how AEC polygons interact with each other. You can join two AEC polygons, create a hole in an AEC polygon by subtracting the area of another one, create an AEC polygon from the intersection of two others, divide or trim an AEC polygon, and add or remove its vertices.
