I must first explain the concept of the software :
The goal is to provide an interactive development. That is, new versions are released quite often (about once every two weeks), modifications, bug reports and improvments are done based principalely on remarks from users. For example, you tell me "It would be cool to have an option that merge two edges by pressing one key", I add it to the current release wish list (if it's not already full), and it is available in the next release.
Right now, the modeler is still in lack of tools, but I think you can already use it a bit. Here are two examples done by myself, and a tester :
You can download the software here : http://www.macrocosm.0rg.fr
The website is in french, but the software is in english, and there is an english part in the forum. You can give your opinion, and show WIP.
Tutorials will be released soon, as well as an english website.
So, come and take part of the development of the modeler !
