Michael,
Thank you very much.
That's really helpfull.
I guess the poly mindset had me looking to create a 45 degree pie piece, followed by iterations. Easy to find oneself in a rut.
My earlier back wall prob has slightly mislead you. The door is solid with pockets rather than cutouts between the webbing. Armed with your example, I'll see if I can construct it again with that variation, myself, and probably be back with more queries shortly. lol Either way I'll return with my results etc. They might be of help to someone out there.

I'm at a loss with that prob though. I've attached an example. It shows two lines at 90 degrees end to end, radiussed. If I then revolve from one end I get the expected cup shape.
However if I double that geometry and revolve it 180 or 360 degrees around the center, one face isnt created. I confess to being a bit vague re the start n stop points, so it's probably user error again.

LOL It feels quite odd to be free of possable rtfm responses! Although I feel a little guilty to be consuming your time.
Thanks again!
Cheers
