Hello, I encounter a potential issue 
I have the liscence of Rhino 7 and saved as WorkSession, then I pass the .rws as well as the dwg files to my colleague.
But the dwg files didn’t open when he run this WorkSession file on his PC (he has Rhino 8 trial version).
Is it because the WorkSession fonction is different between Rhino 7 and 8 ? Thanks
Are the dwg files stored locally on your computer or through a local directory?
All are in his local directory.
I gave him the .rws and .dwg files in a package.
Hello- the paths would need to match exactly - rws files are not designed for sharing
