RemarksThe DisplacementElement does not actually change the location of any model elements; it merely causes them to be displayed in a different location.
An element may only be displaced by a single DisplacementElement in any view. Assigning an element to more than one DisplacementElement is an error condition.
A DisplacementElement can declare another DisplacementElement as its parent. In that case, its transform will be concatenated with that of the parent, and the displacement of its associated elements will be relative to the parent DisplacementElement.
