.sat export issue

Dear Sir,
when i export 3dm to Sat file.
i expert cirle, cylinder…anything with circle/arc object. to sat file.
i can get the center point of the circle or arc.
they will become spline in Autocad.
is there any solution about this issue?

That’s to be expected with .SAT file, perhaps you are thinking of STEP file export?

but, our another software(intergraph Smart 3D) only can accept SAT format.
