GOT IT NOW. was doing it all wrong, now to make the fabric, fun..

IM currently just playing around with a model from 3d warehouse and want to put in a fabric folding sunroof on a vw kombi.

I want it to be from behind the drivers side and down to the end of the last side window.

I tried the intersect tutorial on the sketchup website but it didnt work for this one.

I want the sunroof to be oppen aswell like this http://www.diecastauto.com/catalog/images/92327-Black-web.gif
