I have used Sketchup 2016 together with my 3Dconnexion Spacemouse wireless for moths now, without any problems.
I just installed Sketchup 2017, and now the spacemouse does not react in Sketchup anymore.
I have uninstalled Sketchup 2016 according to the procedure from the manual. I have of course tested that the spacemouse still works fine in other applications.
The 3D Connexion mouse is created by 3D Connexion and they use very specific drivers for the device allowing it to function with SketchUp. If you’re having problems with their mouse you may be able to download an updated driver from their site which will work with your version of SketchUp. If they don’t have a driver yet, be sure to contact them directly to confirm when a driver will be available.
