3Dconnexion is the leading provider of 3D mice to design engineers and creative professionals. Designed to be used in tandem with a traditional mouse, a 3D mouse conveniently streamlines all on-screen navigation, eliminating the tedious shuffle between mouse and keyboard required to position models or objects on the screen. By gently moving the controller cap you can pan, zoom and rotate in one fluid motion with one hand while simultaneously selecting, creating or editing with a mouse in the other.
Independent research has shown that 3D mice increase CAD engineer productivity by an average of 21% resulting in a typical payback period of less than one month. Additionally, more than 84% of CAD design engineers report a noticeable or significant improvement in their product designs and their ability to detect design problems as a result of using 3D mice.
