Hi Igor, for the next MoI v2 release I've updated the SAT export so that it will split closed surfaces (for example cylinders) into 2 halves rather than having a single closed surface that has a "seam edge" in it.

That appears to be one of the major problems with Revit, that it gets confused pretty easily when trying to read in surfaces like that.


I don't know yet if it will solve the particular problems you ran into because I did not receive any files from you to test with... But it appears to make a big difference with getting stuff over better.

It will be possible to turn off closed surface splitting by a setting in the moi.ini file.
