If so - Close down and re-start Allegro you should see the XNets. -----Original Message----- From: Jim Wages <jwages@xxxxxxxxx> To: icu-pcb-forum@xxxxxxxxxxxxx Sent: Mon, 31 Mar 2008 7:39 am Subject: [PCB_FORUM] Re: [SPAM] Re: Exporting Constraints from V16 to V15.5 Hey folks, Did something change in V15.5.1? Now when I try to create Xnets by creating the SI models using the TOOLS >> SETUP ADVISOR tool, I can create all the models I need, but I don't see actual Xnets created. Did I miss something, or am I just missing something obvious? Help!! Jim S. Wages SR. PCB Layout Designer (919) 484-2963 _____ Planning your summer road trip?
