Revit file cannot be imported into the project file

Issue description

A file originating from Autodesk Revit cannot be imported into the project file.

Solution

1. What type of Revit file format is it?

   Is the file in .RVT (Revit Project File) or .RFA (Revit Family File) format? This will determine the import method (see steps below).

2. Link RVT file via Hotlink

   Go to File > External Content > Place Hotlink.

   A file in RVT format is linked into the project file as a Hotlink. Optionally, the Hotlink or the Revit file can then be embedded or the link can be removed via the Hotlink Module Manager.

3. Import RFA file via menu command

   Go to File > Libraries & Objects > Import RFA as GDL Object.

   A file in RFA format is imported into the project file using the above menu command.
