Hi Barry,

Thanks for file - I couldnt Network Surface from geometry supplied maybe if you could just send me the surface only - to give you an idea of the final aim - I am working with another Studio - Studio Kite which have just finished building a large scale 3d delta printer. We are looking at printing textured shells that would form a concrete mould to do spray concrete with. Just as an exercise and a demo of what the technology is capable of.

Here is info on machine

and some concept renders of the proposed structure.
