hmm.. i'm getting the same thing and i don't know why either.. this is probably something fredo should look at and you might want to post this model and explanation of the problem in the FredoScale thread.. i'll mess around with it a bit more to see if there's something obvious i've missed

You need to Scale everything up x10 and afterwards down x0.1, Sketchup and OpenGL can't cope with the small faces that result in such a small object intersection and so nothing gets made... [image: De7J_Capture.PNG]
