Hehe... Colonel Mustard, in the living room, with the pipe. :) I think a generator would be better than an interface with another software package. First, the interface assumes that people have that package or even want to spend the money to purchase the pack. If some sort of basic generator could be developed for Daz Studio that would probably be better as the thing could be used dynamically to create a scene within the render view rather than switching out to something else and switching back again to test. In the end though, it very much depends on which would be the easiest to develop and integrate. From what I've seen so far, most of the home CAD packs for 3d home design are extremely basic and aren't really satisfactory in the end result. Simplicity of creation and quick view results being the intended result. I'd vote for a dedicated generator.
