well i have been using rhino from the 5.0 and for me rhino 7 is real good.
Now moving to rhino 8 have made me think about coming back to Rhino 7.
The last issue i had was when i tried to print a model (from the layout of course).
The output scale failed was a total mess compared with Rhino 7 (working in meters in model space and in mm in layout space…)
