ah well the latest image of opesncad does let you produce rounded sections of a circle, which is a lot more useful than it might sound.

Still not a proper 'bend' or 'curve' command that you can apply to anything. But a definite step forward for those of us who can't get our heads round polygons :-)

Well I've just had a tooth out, so no dog walking tonight, plus it's widdling down with rain anyway.
