It's in the Dynamic plane parameters.

On a negative plane you create a via without a thermal. This makes it a full contact via. The neg plane allows more copper since the contact is based on the hole size versus the outer pad dia. Full contact via show to GND on neg plane Versus a via with a thermal Richard Van Os, C.I.D GE HealthCare -Surgery Lead PCB Designer 801-517-6430 (Phone) ________________________________ From: icu-pcb-forum-bounce@xxxxxxxxxxxxx [mailto:icu-pcb-forum-bounce@xxxxxxxxxxxxx] On Behalf Of Schwartz, Jerome Sent: Thursday, September 09, 2010 10:41 AM To: icu-pcb-forum@xxxxxxxxxxxxx Subject: [PCB_FORUM] Re: Suppressing pads Hope some of you are seeing the issue I am. These are outer layer vias. You can't suppress them and expect the vias to be plated through. I would make them blind vias since the outer layers are foil laminated.

Manufacture => artwork => select your layer. This is in the allegro expert.
