A 3D mouse is a great tool for anyone who works in a 3D modeling program, whether it’s SketchUp, or any other program. It enables you to move the camera naturally and intuitively along 6 distinct axes by pushing, pulling, twisting, and tilting the puck that is attached to the top of the 3D mouse. The 3D mouse doesn’t move across a mouse pad like a traditional mouse, it sits stationary on your desk.
