I am using the 3D Connexion Mouse “Space Explorer” for some years now. The 3D Connexion company marks this 3D mouse as not supported anymore (hence I cant approach them to solve this problem). Moreover, it works fantastic. It works fine with my CAD software (IronCad and Space Claim) and the Adobe PDF. In Sketchup 2017 Pro it does not work.
I re-downloaded the latest driver for the above mouse.
Looking at this forum posts, it seems this 3D mouse issue keeps coming in every release of Sketchup.
Any help is appreciated.
