Accidentally overwritten Rhino file - change it back?

I changed something on the model and saved it, but accidentally overwritten the current file. Can I change that back somehow?

I also have an fbx file from the state I need, but only in polygons and I actually need nurbs: /

Hello - look for a . 3dmbak file in the same folder with the same file name - rename to just 3dm and open that file.


Thank you :slight_smile:
