If main model elements need to reference and update with elements in a secondary option, you must move the main model elements into that design option. Then you can edit the design option to modify those elements as desired.
The main model consists of the entire building model, excluding elements in any design options.
Elements in the main model cannot host or reference elements in secondary options. Therefore, elements in the main model do not change their shape or properties when you are looking at a view for a secondary option. For example:
To move elements from the main model to a design option set
Revit lists the design options for the selected set.
If you clear a check box, the elements are not added to the corresponding design option.
Copies of the original elements are now in all selected design options in the set. The original elements are no longer part of the main model.
