Hi Arraythank you for your help. I will check that.nI have another question. When i import my design from altium to HFSS 3D Layout (by using ODB++ files) i can clearly see that in my list of IO components there are the connectors. I also have a 3D cad component of this connector.nMy question is can i in some way map the 3D cad component onto the IO component and simulate this?n
