Yii2 UML code generator

Howdy!

I am a master student. I’m doing researches for my future dissertation. Thesis will be advanced code generator from UML source. Actually, there several solutions for php, but they they allow you to use only the basic features of UML.

Have you ever use such code generators? Which one? What problems you faced with?

I’ve tried http://www.visual-paradigm.com/ long time ago. It kinda worked.
