Is there any specific to be done to export an imported DXF as SAT?

Hello,

I have imported a DXF with 3D data into Draftsight. I can turn and shade it properly (although turning only via key in in the command window)

But there is no possibility to export as SAT.

Selecting the region after command "exportsat" gives a lot of found objects but then nothing happens.

Do you have any suggestions?

regards
