Although most file formats are exported seamlessly to Content Catalog, there are a few formats that take some extra steps. Here are some workarounds to help you add that content to Content Catalog:
Spot Coordinates
Since spot coordinates are more of a function in Revit, they are not directly saveable like most items we can export from Revit. You can, however, save the actual symbol for the spot coordinate.
Curtains/Mullions
To add curtains/mullions, batch export the curtain wall or curtain system.
Filled Regions, Line Weights & Line Patterns
To add filled regions, line weights, and line patterns to Content Catalog, lay all of them out on a drafting view and batch export that drafting view.
3D Views, Plan Views, Sections, & Elevations
To save these, you could create a template (.rte) file or a project file that you save. Keep in mind that it wouldn’t be specific to the model elements; it is just going to show where views are oriented, what they are looking at, where they are cut, etc.
