Please evaluate the attempt to automate the calculation of packaging models from cardboard. The generator is designed as a simple alternative to expensive and cumbersome applications. Calculate packages based on ECMA templates. Is not CAD application. Algorithms for 178 templates are now working and new ones added periodically. All models were tested on different types of cardboard (not corrugated cardboard) with a thickness of up to 0.4 mm. The site is under construction, has a minimal design and the generator is in test mode. Any criticism is taken.
