Hi, When I try to preview or render this code: difference(){ circle(r = 100); translate([10, 0, 0]) circle(r = 100); } On my computer, I see a crescent, as expected. When my friend previews or renders it on his computer, there's no model. We both have version 2015.03-2 running on windows 10. Any ideas? Cheers, Will

Initially, I could not see the preview, but 100 units out is beyond the default view for the preview. After I clicked the zoom-in icon a couple of times, there it was. I don't know if that was an issue for your friend, but...

I had to zoom out to be able to see it. If your friend is a novice that might be the problem.
