Build a interactive 3d website. -- 3

MUST SHOW PAST 3D WEBSITES I need 3D interactive website where customers can build whatever they want. it must give configurations on how to pack item from the different size parts. I will have about 100 items that people can purchase and design there own custom cat house. People will be able to construct exactly what they want in there home. I would like to be able to add different furniture as well so people can get a real good look of what it will look like in there house. there will be 3-5 different color faux once people have purchased all the parts they want. if possible, I would like the computer to tell us how to pack it in box. the different size boards and parts. I have attached example of what they can build. they can always add on and on to there design. I would need shopping cart with Shipping calculator Have you done this type of job before and if so, what is the website you designed Thank You
