Missing sidesets in Nastran(.bdf) export

Hi,

I’m using v 2022.4 on Mac OS 13.

I want to export a quad8 mesh to .bdf, in order to import it in Gmsh.
I noticed that if I export to bdf and then import the bdf in Cubit, the sidesets disappear…

Could you please let me know if there’s a fix for this?

Thanks.
