I am working in Revit 2024.2  
I have a Revit model with 2 design options. When I switch between them, the materials in the option set default back and I lose whatever materials I’ve applied to them earlier. How do I stop this from happening?

You must import both models separately, and if you’re going to re-import, you should re-import the same one from both files. When exporting, make sure each export matches the model with the file name it belongs to.
