Title: kicad via stitching being wierd
Post by: hazuki on December 10, 2014, 08:35:16 pm
Hi all. I am trying to stitch two planes together in Kicad. It seems rather intuitive and works properly. However, after working on another part of my PCB, I come back to the area that I've just stitched and all of a sudden the pour around the vias are removed, effectively isolating them. This problem keeps happening to me, and I don't know why. Anyone have the same issue? Both planes are on the exact same net. Here's an image of my recurring problem:

Thanks!

When you start make sure the first node is connected to a real pin for example the D pad on the transistor/fet.

When the ground plan is regenerated or DRC is checked, it destroy the original copper flood and the track/vias are disconnected form any net. Then it is regenerated resulting in what you have here.

I know really annoying.

Are you on one of the old versions, or a recent testing build? If the latter, shut off DRC, manually reconnect the via, and then re-import the netlist.

As king says, tracks don't always keep their net associations; they have to be anchored to something with a netlist-defined net.

King,

Thanks, you've solved my problem. Kind of annoying, but I can deal with it.  :-+
