I have a 3D Connections Space Mouse that I use on several different CAD software systems with no issues, but after installing 2015 Sketchup on ;my system I can’t get the space mouse to work with this software. Thinking that the free version didn’t work with the space mouse I purchased the 2015 Sketchup Pro version, but still no space mouse. Even downloaded the latest 3D connections software driver that says it compatible with Sketchup 2015 but still no space mouse. ;
I had the same problem but after downloading the latest driver, x32 or x64 depending of yours spec, and reinstalled after sketchup is installed.
