As of Revit 2024, the end user can change the location of their collaboration cache through the UI. Is this location available in the API? If so where can it be found? I thought I had found it before but I don't see it now.
The collaboration cache location is stored in the Revit.ini file:
[CloudModelCache]
CacheLocation=C:\Users\hume\AppData\Local\Autodesk\Revit\Autodesk Revit 2026
It takes effect in the next Revit session after update, so it may not be a good idea to expose it via the Revit API. The workaround is to overwrite the contents in Revit.ini. For read access, this solution is perfect.
