Hello Ralf,

most of the nodes and the functionality of the extension are build by a user request or a missing functionality of the core. Max can't write everything by itself with respect to his time and work on the core. The different aspects of use for such an application is a wide field. So it's not only a tool for generative geometry creation, its also a generative process to get the tool. The documentation was not in the focus. I tried to start a wiki, but I was the only one who wrote something. Nevertheless there is also an outdated Excel sheet where you can look for some functionality:

Maybe the menu position had changed, but node names and functionality should still work.

Have a nice day
Karsten
