To edit the geometry and settings of an Opening element, you must first reserve the Opening.
For example, the following interactions require that you reserve the Opening:
•Cut additional element
•Delete Cut element relationship
•Redefine the Opening’s associated element (reassign Pin)
However, you do not have to reserve its associated or cut elements. For example, you can create new Openings in elements that are part of a Hotlinked Module without reserving them.
