While using layouts and viewing in technical mode I am getting random geometry appearing ?? If I switch back to say wireframe the random geometry disappears ??
Please post three things:
- a screenshot that shows the problem
- a screenshot of the settings in Options > View > OpenGL
- a small 3dm file with the offending geometry
Maybe there will be a clue we can spot
@John_Brock 2 screenshots below, the file is quite large, I have had this happen a couple of times in the last week or so, it’s making my layouts look terrible 
It only seems to be affecting the top view, other elevations seem unaffected ??

How does it look in the V6 Beta?
@John_Brock not tried in V6, but I seem to have sorted it, I went in the options, display modes, technical view, there was a box ticked, ‘intersection’, I unchecked that box and the offending geometry disappeared, it’s strange as I have only encountered this problem over the last week or so, maybe there’s a ‘ghost in the machine’ somewhere in there
