Hi Michael!

1. Re analytic output: (shown below)
If I change section parameters to y (both or one by one) SAT file is not exported at all
[NURBS Export]
WriteAnalyticCurves=n
WriteAnalyticSurfaces=n
So SAT file can only be exported when both parameters are set to "n"

2. One model for exports from Rhino and Moi to see difference in SAT files:

The Problem comes from MoI 3dm because:
If I create .3dm file in MoI - no matter where I export from to SAT (from Rhino or MoI) - export doesn't work properly.
If I create .3dm file in Rhino - no matter where I export from to SAT - export works just fine

Therefore I cannot give one .3dm model and 2 SAT files exported out of it, instead I have created identical shapes in both Rhino and MoI to be able to generate both bad and good SAT export

pls see attached (also import dialog - but nothing really changes there from import to import)

Sorry for this problem, hopefully you'll be able to fix it

Regards, Igor
