Weird. Not working here. I have polygons on top and bottom layers, both on GND net. I drop a via on a blank spot, and it picks up the GND net just fine. I can verify that in the properties for the via.
I then redo the polygons, they rebuild, but the via is isolated. But it still has the GND net associated with it, and there's a rats-nest line leading to the nearest pad on the GND net. If I select the via, the whole GND net is highlighted as you would expect. Even weirder, DRC doesn't flag a Broken Net error ... The polygons have correctly attached to all the GND pads on the various components, just not the via. The polys are definitely good - they're providing connectivity all over the place for GND. Dropping round pads with the same dimensions works fine. What the <bleep> ? PS - what's the "Minimum primitive size - Length" box for in the polygon properties dialog ? I've never messed with it - I think it's always set to 2mil. -- Dean Carpenter deano at areyes com 94TT :) ----- Original Message ----- From: "Dennis Saputelli" <[EMAIL PROTECTED]> To: "Protel EDA Discussion List" <[email protected]> Sent: Tuesday, March 08, 2005 6:56 PM Subject: Re: [PEDA] Weird - via won't join GND polygons > vias connect fine to pours > > i do it all the time > touch or place the via on a grounded pin or pad, then drag onto pour > > if you place them initially directly on the pour sometimes they pick up > the ground net and sometimes they don't > > sometimes just wiggle them on the pour and they pick it up > > not as much of a bother as it sounds > > and/or select them and global edit the net name to 'selected same' > > nothing wrong with your named free pads method though, we do that > sometimes too > > ds > > > _______________________________________________________________________ > Integrated Controls, Inc.
