Hello!
Thank you @mcmillr for response!
Fusion 360 is strongly used in game dev companies for creating hard surface models. It gives a possibility to achieve awesome results which are hard in traditional modeling solutions (for example poly-modeling in 3DS Max). Also its non-destructivity is very desirable because we can make changes in our designs any time.
Simplification tools will be very useful in exchanging high poly model (model with fillets, chamfers, very high quality) to low poly models which are optimized for games (without fillets etc. geometry is as simple as possible). Then we bake all the details from high poly to low poly by normal maps.
Example how it looks like: http://www.chrisalbeluhn.com/Normal_map_tutorial/Image_31.jpg
Simplification tools will give us an opportunity to achieve good results almost by one click. It will be very helpful even only in Simualtion mode (if implementing in Model mode is hard) but with quick .STL export ability.
Your workaround works perfectly, thank you! Of course it's a bit slow method, but it works as we would like to.
It would be incredible if Fusion 360 was a bit more adjusted for game art not only engineering.
Thank you!
Have a nice day!
