So..(remember, I'm new...)...

Do the models that you create have their own "format" or is this just part of how the file itself is saved.

Using your favorite rendering program, then, you just import that file then, right? Does it come in as it's own object where you can then manipulate it in a scene or does the whole scene import?

What I mean is, when you have, say, an interior scene with 20 or so different objects, and then you want to render it in a differnt program, do you make each object individually and then arrange them in the renderer? Or do you arrange the whole scene in the modeler and then just have the renderer do nothing but, well, render it.
