**** BUMP
I had problems with zooming/scrolling with my Apple Magic Mouse 2, and thought there was surely a way to resolve the zoom 'resolution' but couldn't find a good solution suggestion.
Well... here it is!
I just bought a Logitec MX Master 3 and even without the Logitec software, I can now zoom with the scroll wheel almost by a single % point in both plan view and 3D.
Absolute game changer!
So I'd highly recommend buying a serious mouse to work with Vectorworks, hopefully, it will help with hand cramps too!
