Hi,
I am trying to cut doors and windows into a Poly shape made by extruding faces, the wierd thing is that when I go to Polygons>Boolean>Difference it deletes the while lot. (Not just the hole I have my Cube around) - The whole thing dissapears, cube and all !
Any ideas?
[It seemed to work OK on 1 'wall' it just happened when they were all connected]????
Just noticed it says:- "Problems resolveNonSolidShell" in the output window...

Regards
