Hi Burr,

> the translation of MoI's surfaces to other apps, will result in "Shrinking the trimmed surfaces"

That only happens with SAT format export, as a side effect from splitting closed surfaces. It's something that you can turn off, if you go in moi.ini and set:

[SAT]
ExportSplitClosedSurfaces=n


It defaults to splitting turned on because I originally added SAT format for transfer into Revit and it did not like to handle closed surfaces in there.
