## What is Gear Design?

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.

## Key features

- Involute gear design
- CAD interface
- Touch gesture controls (zoom, rotate)
- STL data generation
- Email export

### 1/5 — Majorly Disappointing!

*2023-08-30*

"Gear design" is a letdown on multiple fronts. Why can't we export CAD files directly? Being forced to email them to ourselves feels like a needless step back in technology. The almost non-existent instructions leave users fumbling in the dark, and restricting measurements to inches in today's global landscape is inexcusable. There's a lot that needs fixing here.

### 1/5 — It does not have cm

*2020-04-04*

It is not was i was looking for. Why does it matter if you can calculate the forces if you cannot set wheel diameter¿
