Hi Matt,

Have you submitted the file to Altium for inspection?
Did you ever get a resolution to this one?

Tony

Subject: [PEDA] HELP!! Gerber Output Contains Random Subtle Errors With
Plane Connects!


         Hey Gang,

         We've come across a *major* show-stopper problem on some boards we 
just got back from our board house. For whatever reason, there are a few 
spots where DXP decided that our vias should just not randomly connect to 
the power planes their nets are assigned to. Most of the board is fine, but 
we've already found one major cluster that's problematic. Take a look at 
this...

         http://www.raven-systems.com/temp/missing_connections.gif

         As you can clearly see, when viewing the power plane connections 
in the layout editor, the interconnects show fine. When viewing the 
verbatim generated Gerbers, however (RIGHT IN DXP!) there are missing plane 
connections! The entire top set of 7 vias are not connected to ANY planes, 
whilst the bottom row are connected just fine where appropriate. I looked 
at the properties of all of the top-row vias, and they're just fine - 
nothing out of the ordinary. Surprisingly most of the other vias on the 
board (including the bottom row) connect just fine!!

         Has anyone seen this, or know of a way to have DXP scan for it, or 
fix it? We just lost a lot of time and money on this spin-and-assemble due 
to this export problem, and I have a feeling we'll likely be finding more 
of these little via issues as we continue to bring the board up. And worse 
yet, we have to do another Gerber generation - am I going to have to 
hand-check several thousand vias on the Gerber outputs to ensure this 
doesn't happen again?

         Honestly, this is bringing me to an absolute last straw in 
continuing to use Protel if we can't even be guaranteed consistent WYSIWYG 
output. Someone PLEASE tell me we did something wrong? I'm starting to lose 
patience with Altium's little "features" in the software.

Frustrated as hell,
-- Matt
