Well, I go to presented my addon
An example where I used my addon is this weapon: skfb.ly/69Z7O
Previously it was called mychamfer, but now it is called Game Dev Tools. It is based on the workflow used with max, but in a much more practical and easy and fast way.
This is useful to facilitate the workflow of creation high/low poly for hardsurface modeling, for creation of video games, with substance painter, more easily.
Here is the complete playlist of the addon to see more features: youtube.com/playlist

I am the creator so suggestions and feedback are welcome. Regards!.
