Anyone any ideas why the brickwork above one of the arches fails to show on the print window but does appear on the setup window? The brickwork has a depth of 0.3mm. Ignore the thin diagonal additions on the setup window, I can get rid of that!

Sorted the problem out now. There was a gap between the bricks and the face of the wall. A gap of 0.0001mm!
