NX Help - PCB Exchange section says that "Non-circular cutouts can be tagged with drilled hole attributes only in PCB Exchange for Zuken and IDX.", I know, then the only way to exchange non-circular cutouts between NX and ECAD using IDF is that user must not tag any definition to non-circular cutouts i.e. they are defined as a part of "Outline Section". It means that you cannot exchange the plating style infomation ( thru / non-thru ).
Are there any workaround for this situation?
