Hey everyone, I have seemed to have stumbled across a bug when exporting a PNG using sketchup Free.
So I get my drawing all ready to export as PNG, hide all guides & axis. Then click export. Then it shows the preview of the export, and all of the guides and axes lines are back. I can not disable them, and when i follow on with exprting, the PNG does show the lines, so it's not just a preview glitch.
