Hello, I deal with this all the time.. The best way I found to handle it was to define a small static shape on top of the via with the net name attached to it. This shape is defined a little larger than the via geometry on the top side of the PCB and whenever I move the via I make sure to select the shape as well. Kind of a pain but it gets me past the problem. Maybe someone else has a better way of handling this.

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. Thanks for any suggestions Daniel So email: danielso@xxxxxxxxxxxxx (See attached file: C.htm)
