Rats nest on all GND connections, despite existing GND plane

split63
split63 over 17 years ago

I have completely routed a small board manually.  The only "opens", as indicated by the Rats nest lines, are all the GND connections.  I have a negative inner GND plane and each connection has a through-hole via, so why are the GND nets not finding the plane?  Is there some command that must be issued to cause the vias to find the plane?

 Thanks,

 

P.S. Under SETUP -CROSS-SECTION, it lists TOP, GND, Layer 3 and Bottom.   On the Visibility Tab, Under view, it lists Film: Top, Film Layer 2, Film Layer 3, Film bottom.    Not sure if the two should match

    Way too little information to form an accurate reply but, I guess the product is PCB Editor, which version? Let's assume 16.x, set the plane to +ve artwork, ensure that it has a dynamic copper shape on it and that this shape is connected to the correct net, THEN you should see full contact vias and thermals on through holes, assuming "default" settings, and you might start to get somewhere.
