Restoring a Body Modifier to a Mass Element
Use this procedure to remove a body modifier from a structural member 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 structural member 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 structural member. This is useful if you want to create other structural
members 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 cylinder mass element is
restored as a cylinder 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.
