Sometimes changing your planes to negative helps with this.... The vias always seem to get attached to the positive planes -----Original Message----- From: icu-pcb-forum-bounce@xxxxxxxxxxxxx [mailto:icu-pcb-forum-bounce@xxxxxxxxxxxxx] On Behalf Of Daniel So Sent: Thursday, March 02, 2006 11:44 AM To: icu-pcb-forum@xxxxxxxxxxxxx Subject: [PCB_FORUM] Retaining nets on free-standing vias Hi Everyone Please excuse me if this is an old subject. I have thru-hole vias connected to a gnd plane on the top layer. There is +5v plane on the bottom side of the PCB. There are no clines connected to the vias so when ever I move the gnd plane, the vias are now associated to the +5v plane. I now have to move the +5v plane before moving back the gnd plane if I want to keep these vias associated to gnd. This is really a bad problem on a multi-layer board with different planes on different layers and when I have vias that I want to keep associated to different nets. Is there any way to keep the vias associated to the original nets without connecting clines to them? Cadence did not have an answer.
