Hi Again,
going fullscreen on startup seems to have got rid of gui errors : ) you were absolutely right that the bevels weren't working due to how the seam edge on one sphere was hitting another accute angles gave me an error.I'm now getting something unexpected using the arc tool and sweep . If I use the freeform tool to make a curve it seems to work, but I'm unsure why it does not work with the arc tool.

Thanks
