For the last couple of years I have been using two devices that I find incredibly useful and valuable. They are both from a company called 3DConnexion. One is a 3-button mouse called CadMouse. The other is complimentary directional knob/joystick type device called SpaceMouse Compact. The devices the company sell are designed around CAD and CAD-like programs. Sadly the SpaceMouse is not fully functional with HCE yet. In regular CAD software it allows moving around in 3D-View but it does not in 3D View HCE. The 3-button CadMouse works perfectly in all views of HCE. I have both the wired and wireless version but my preference is wired connections when working at my desk station. Does anyone else use them or like devices?
