Sorry there's been no updates, real life has been rather brown, dealing with a death and a near death.

ghostman - yea they are a PITA especially the clean up. Especially if I forget to use the merge command on the mesh before trying a Boolean. That's guaranteed to get the dog leaping my lap to offer some intensive therapy :)

Sam - thanks - though at this rate it'll be one for the history books by the time I've finished it :)

Warlock - thanks so much for that, not sure what you mean by edge flow, shear/proportional move tool.
Not sure if Carrara has the latter two or not. But your image has certainly saved the day here - literally in seconds!

Dunno what it was but for someone reason when I restarted this yesterday, I just couldn't grasp your idea. obviously, my brain being full of stuff, not your excellent suggestion. Just seemed to go around and around in ever frustrating circles, so I left it and started on another part.

Then I decided just one more try and bingo it worked, so thank so much!

Pinky - you left the lens cap of your mind on again.
