Hi Al,

interesting post! I can understand that your are not happy with the result. My friend Jotero
did this probably once as an excercise with MoI. The proper way to produce an accurate
Batwing Minimal Surface is however to use Ken Brakke's Surface Evolver, with his batwing.fe
file, which can be exported as .obj from Evolver.

If you are interested i can post an accurate Evolver file conversion as NURBS model, of
Ken Brakke's Batwing Minimal Surface, when i'm home from work.

Due to the nature of surface tension etc. of Minimal Surfaces regular Poly Modelers
or MoI/Elephant etc. can't produce an accurate representation of Minimal Surfaces, IMHO.

Regards
Stefan
