To Restore a Body Modifier to a Mass Element

Use this procedure to remove a body modifier from a stair and add it to the drawing as a mass element. Restoring a body modifier to a mass element enables you to modify the shape as a mass element and then add it to the stair again as a body modifier. You can also restore the body modifier to a mass element while leaving the body modifier still applied to the stair. This is useful if you want to create other stairs with the same shape.

If the object used to create the body modifier was a conventional mass element, it is restored to that mass element. For example, a Gable mass element is restored as a Gable mass element. However, if the body modifier was created from another object, such as a slab, or was edited using Boolean operations or face editing commands, the body modifier is restored as a Free Form mass element.
