Not sure how many of you design in 3D but I though I would just throw this out there. I just got a 3dconnexion Space Naviator 3d Mouse. All I have to say is where has this been all my life!. I design my projects in Sketchup for the most part but it works equally as well in Fusion 360 and others. Takes a little getting used to but once I got thins configured the way I wanted I was off and running in 30 minutes. I like it so much I ordered a second one for my other computer.
