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:
- If you sketch 4 walls in the main model and then sketch a roof in a secondary option, you cannot attach the walls to the roof.
- To add a skylight to a design option, the host roof must also be part of the design option.
- To add a door or window to a design option, the host wall must also be part of the design option.
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. (See Referencing Elements in Design Options.)
To move elements from the main model to a design option set
- Open a project view that shows the elements to be moved.
- Click Manage tab
Design Options panel, and select Main Model from the drop-down list. - Select the main model elements to move.
- Click Manage tabDesign Options panel
(Add to Set). - In the Add to Design Option Set dialog, for Add selection to, select the desired set.
Revit lists the design options for the selected set.
- Select one or more design options to which you want to add the elements.
If you clear a check box, the elements are not added to the corresponding design option.
- Click OK.
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.
Tip: You can also add elements to a single design option by cutting the elements from the main model and pasting them into the same place in the design option. Use the Cut and Paste Aligned tools, as described in Moving Elements from One Design Option to Another.
