I recently downloaded rhino and was able to zoom and pan. For some reason it stopped worked. I did not change any settings. I tried restarting my computer as well as trying command_zoom. My mouse is working fine so it is not related to that. I have seen multiple other people report this issue and I have not seen a clear answer for anyone. Need help asap!
In the Rhino 7 pull-down menu under Settings/Preferences > View, is your Zoom “Scale factor” set to 1.)?
Try 0.9 or 0.95
That worked! Thank you so much for your help John!
