Opening Rhino 7 files in Rhino 6

[markleichliter]

I just ran across this on the forums:

Rhino 3dm file version converter

This utility makes use of Rhino3dm.NET, which is licensed under the MIT license. Therefore no Rhino installation is required and 3dm files from Rhino 2-8 are supported. DO NOT SAVE FILE IN THE SAME LOCATION. Rh3dmConverter.zip (7.5 MB) [image]

Maybe this can be of use if all else fails?
