Hello Guys
Sometimes, the editor fails to load all windows in the project. As a result, the material selection appears empty, and no windows can be added.
i can not choose Unset Material
After restart of Revit and Pollination it works
Yes its an imported IFC
Yes there is an error message (timeout)
I will PM you the model.
I think I tried that before and also performed a hard reset (setting).
Only a complete restart of revit and pollination solved the issue.
