Hardly anything in Away3D is documented.

I can see it has lots of features, but they are completely useless without proper documentation.

Can someone on the team just quickly go in and explain each and every method and class?

Even a quick explanation would go a lot further.

Once that is done, examples and diagrams and a general overview of concepts would be great addition.  The priority though should be to quickly outline each class and method though.

Agreed. That is the biggest shortcoming of the framework.

Of course, you can get the gist from examples ( much better documented, but still not API reference, is it ? ), but dig any deeper and you’ll need advice.
