Sorry I can't explain it very well! I have attached a screen shot - the shelving and tables show all the green construction type lines, as does the circular structure at the back of the shop and the mirror. When I look at it in 3D view these lines do not appear, only when i save the image or put it on a page layout. Also, the right wall is actually white, but shows up as grey. Not sure why this is happening either. Any help would be greatly appreciated! Thanks.
