Interference Conditions Created from 3D Objects
Interference conditions use the geometry of 3D objects to create custom
openings or cutouts in walls. You can specify how the interference condition
is applied to the wall: added to the wall, subtracted to the wall, or ignored.
Interference conditions apply to all wall components that the interfering
object touches. The wall stops at the interference condition. The way in which
you apply the interference condition to the wall determines how the
shrinkwrapping of the wall is affected by the condition in plan view. In model
views, the interference condition is always subtractive, regardless of the
shrinkwrapping option you selected.
When you edit the object that acts as the interference condition, the wall
changes to accommodate the changes to the geometry of the object. For
example, you can move the interfering object to change its location on the
wall.

Working with Wall Sweeps
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.
