How to save/convert HFSS 12 file to HFSS 10 file?

I drew a model using HFSS 12. I need to send the file to my friend (on the other side of the world) who is using HFSS 10. Any idea how can I save or convert my file to the older version so that my friend can open it without any problem?

It's pretty urgent. I would really appreciate if somebody can give me some hints. Thanks!

Hi
I don't think it is possible to convert HFSS 12 file to previous version.

Hi zingkov,

UNfortunetely you can't convert into older versions, BUT what you can do
is export the hfss 3D model in .sat or .sm3 so that your friend could open it
without any problem by using the tool import in hfss, then he will have to
reset the boudaries and excitations but the design wil be here.

Hope it helped.

Regards.
