Gearotic Motion is primarily a Gear Template Generator. Its true purpose is to create dxf's for further processing by various CAD/CAM programs. It has capabilities far beyond just creating DXF's though, it can produce 1:1 scale printouts for scrollsaw gear cutting, STL files for 3d printing, 3d solids for various CAD usage, and finally G-Code for users of programs such as Mach3. In addition, it has a graphic simulation mode that allows the user to think about how to make a device, or determine other factors he may want to consider. It will provide some statistics about gear ratio's, sizes , centering and such and is a fun, easy to use mode that is virtually drag and drop for mechanism creation.
GM now includes a second program codenamed during development as Gearotic Thoughts. Its purpose is to ensure closed manifold STL's for 3d printers. IT is very handy for printing pulleys, gears and mechanisms for 3d printers and will eventually replace GM.
