Sketchup Problems

Can anybody tell me what I’m doing wrong with this sketch up file I’m trying to import.
For some reason the right hand side is greyed out and doesn’t reflect the same as the left hand side. Is it some sort of mask layer ?
And is there any way of getting it to look like the original once its loaded into MSD ? instead of it looking like a primitive CAD drawing.
I don’t have the luxury of AutoCAD etc so having to use sketchup.
Cheers peeps

I suspect that it has to do with mirroring. The right part is probably a mirrored copy of the left.
Can you e-mail the Sketchup drawing to us ( ) so we can have a look and maybe fix it ?
