I have been developing an add-in for Revit that allows users to visualize and place families without needing to access the Project Browser. In this add-in, our administration manages which components are permitted in specific projects. We aim to include system families in the add-in to control which system families can be used in specific project.
How can we add system families in the add-in? We cannot edit and extract system families from Revit using API nor from the UI.
