A wall sweep is a wall or a wall component whose shape is extruded horizontally from a profile that was created from a closed polyline. The profile “sweeps” along the length of the wall to define the shape of the wall.
The height and the width of the polyline you use to create the profile define the height and the width of the wall component.The profile is not scaled when swept on the wall. The insertion point of the profile becomes the lower-left corner of the wall component.
After you create wall sweeps, you can miter wall sweeps that meet at a corner. You can also change how the sweep is applied to the wall:
