Again, a big thank you James

The actual project is for a chair company. The chair is made up of back rest, seat, pole, foot rest, base and trims. They are for the casino industry and I want to be able to "make" up a chair choosing different parts then email a screen shot. The screenshot so far will have to be saved on the users machine then attached manually and emailed.
So I should setup a blanck scene with a BG image. Then add all the other parts individually in their own scene. Clicking a button in the main scene will....hmmmm. That's not going to work unless i can load multiple another scenes into the main one & position them. Maybe adding all the elements to the main scene and working with thier opacity would be the best?
Whaddya think?
