You can change a selected frame edge or mullion edge by using an edge assignment override.
Note: To exchange a frame edge or mullion edge, the new edge definition must already be defined in the door/window assembly style.
Removing the edge does not affect the width of the cell. To remove the edge and have the adjacent cell resize, create an edge definition with a width and depth of zero.
You can also create a new edge profile by drawing a polyline or using an existing profile in the drawing. This edge profile can be interactively edited on screen by in-place editing.
