HFSS-IE projects - Ports definition on IE - copy HFSS Design into HFSS IE

Hello,

Two questions:
1. I have a coax structure that I would like to use as a port. How do I define the port in the HFSS-IE?
2. How can I (easily) transform an HFSS_design project file into a HFSS_IE. I'm told that a copy & paste of the objects would just do it, but I do not how to do that. (I tried and couldn't find a spot in the IE to paste it.

Thanks

Kato
