How to modify properties on existing objects, such as Windows, that are in a Reference attachment?
The modification of building elements which are in references can be done in two ways:
1. You can modify the element properties by activating the associated reference to which the elements are attached. After activating the reference, the Modify options such as “Modify Door”, “Modify Window” etc. will be available. Thereafter you can modify the element as needed.
2. Another way you can do this by Bi-Directional Operation, which is simply the exchange of data between the Schedules dialog and an Excel file. You can update a project entirely from the Excel file which aggregates all of the building data from that project. By editing any element you can reflect that change back in the project.
