To Subtract a Body Modifier From a Wall

Use this procedure to create a 3-dimensional (3D) body modifier and subtract it from a wall. You can apply the modifier to a single-component wall, or to a component in a multi-component wall.

You can create a body modifier from a mass element, a mass group, or any other AEC object with mass. You must place the object in the location you want in the drawing before defining the object as a body modifier.
