What is TracAhead?

TracAhead is a small USB HID device. When you plug it in, your operating system reports it as a 3DConnexion SpaceMouse Compact, and CAD applications that already support 3DConnexion devices (FreeCAD, Fusion 360, Blender with the 3DConnexion plugin, SolidWorks, Onshape, etc.) work out of the box.
