Objects vanishing out of file ...

Hi there,
i am quite new to MOI and NURBS modelling. Because the project i am working on
is already there as a poly model, i am importing it as a SAT file into MOI and use it
as a sort of 3d tracing source, which works quite well.
Unfortunateley are some parts (most of it) of the imported model gone, after saving
and reopening the MOI file. I dont understand, why that is happening?
Aside from that i would really apprechiate a import option for OBJ. Is there any way to
do that right now, or might there be such an Option in a future version?
Best regards
Heiner
