Thanks jolran, I will definitely give that a go!

Csaba, you're good. That's exactly what it is. If you move the groups up in the Z direction a little bit, this won't happen. And if you switch to Parallel Projection, the height difference won't show.

Brilliant, thank you very much!

Are those groups right on top of the surface (face) of the road? I am smelling some Z-fighting here. Could you attach a sample file as well?

I have uploaded a sample file, as requested.

Hi

When I have a drawing which I am sending to LayOut and i am losing some of the colours. They show up just fine in SketchUp but not LayOut. I guess it has something to do with the groups because the two sets of white lines that show are in groups. The others are also in groups, but not working.

Thanks

Jonathan

Hi

I have been having a problem with Sketch Up ever since I have started using it. When you put colour over other colours i end up with one of the colours breaking up. At the moment I am tracing a road, I have attached a screen shot. I have also had the same problem with drawing in 3D. If any one could help me that would be much appreciated.
