I'm fairly new to the forum, but I've searched through the previous threads and didn't find an explanation on how to create objects (or classes). I understand how to add (instantiate) an object. But I want to know how to create a new type of object. I've seen the cool objects that are being shared, like the lego darth vader, guns, etc.

But what are the ways to go about making those. I read that they can be imported from other objects or formats. How does that work? What format or type do they have to be to begin with and how do you covert them to a2c files. Also how would you go about creating a 3d object from scratch? Do I need another 3d program to create them, or can I do it in Alice? Not including the he/she builders etc.

Any links to previous threads that explain this, or other programs that can be used, etc. Would be appreciated. Even if you can just tell me what I am looking for.

Thanks.
