Gear Design vs Area and Volume Calculator Usage & Stats

Gear Design is great in designing involute gears from scratch. Application includes a CAD interface in front end where users can assess designed gears visually with their finger gestures (zoom, rotate, twist etc.). Users can easily generate STL data of the CAD model and export them via Email (Two step action: first generate data and then export via Email). Tooth bending strength analysis calculator is included with multiple sharing options, including a pdf file.
