Thanks Drake.

Both for encouragement and for the pointers both to Dmun's design and to the Building Regs. It is 2.3m here (7' 9"), I have just checked, and I can keep that distance, I'll just make the "shelf" stick out a bit more.

My work with Sketch-it is rather rough, OK for the very first attempt of someone who never used a CAD before, but that's it. There are some odd lines across, walls with zero thickness etc., but gives the idea. I'll work on this. I need to work out how to draw a dome now!

All the best,

W.
