Any WIP?

While waiting for your comments on constructing the torp door, I've mucked about exploring a test object trying to break down an approach.
I don't understand why I can't seem to generate the back wall center, even though it was selected with the other bits that have spinned into surfaces.
Also I'm at a loss how to create the inner faces of the 4 pockets between my webbing? Ideally the webs should be radiussed on all intersections.
One thing for certain, I'm giving the radius tool a workout. So far its great.
Cheers
