Proportions - Sphere worlds impossible?

[PvK]

Oh, interesting additional information, and good suggestions for alterations! Thanks!

I wonder what the limit is on the materials requirements.

Supply requirement should probably be zero anyway since one generally needs a base which by SE4 definition has infinite supplies.

I'd also be interested to see your save game file or hear about what it took to get to the point where you were actually building these things!
