To Edit the Geometry of a Body Modifier

Use this procedure to edit the shape of a body modifier that is attached to a wall. You can edit the body using grips to edit faces, using Boolean commands to add or remove other objects from the body modifier, and other editing commands to change its shape.

1. Select the wall that has the body modifier you want to change.
2. Click Wall tabModify panelBody Modifiers drop-downEdit In Place.

   A temporary mass element is created for you to edit the geometry of the body modifier. If the wall contains multiple body modifiers, a mass element is created for each body modifier. If object was not originally a mass element (for example, if you used a slab as a body modifier), the object becomes a temporary Free Form mass element with faces that you can edit.

   Note: After you perform an editing task, you may need to select a profile again to perform another editing task.
3. Edit the body modifier:
