I found that pan and zoom on a mouse (pushing the middle scroll wheel to pan and scrolling to zoom) was so fast and intuitive, that I abandoned the trackball. Drawing freeform clouds (or lassos with other apps) around objects was just a little harder too. Being able to manipulate the track ball between the thumb and index finger made it very precise for pointing, but like many other trackballs, the left-click is with the thumb, which seemed less direct to me for "point and click" operation. Many years ago, I tried the Logitech Trackman Marble FX with AutoCAD ( ). Totally agree, "whatever works for you".For the half dozen engineers on my team, every one of them does things a bit differently, whether mouse or trackpad. There is no one right way, just whatever works for you. I use a 3Dconnexion Space Navigator for SketchUp.īut to each his own.

I also use a wireless trackpad because some actions are quicker on it (I use an iMac). I currently use a Logitech M570 wireless trackball. My index finger is busy with the scroll wheel and the buttons. Unlike some of the commenters, I prefer using my thumb. I don't miss having to push a mouse around, constantly having to pick it up to reposition it. Then a colleague turned me onto trackballs, and I've never looked back. I spent many years happily using a mouse to work with AutoCAD.
