[PCB_FORUM] Re: nets shorted to gnd plane

Sam, 
 
I assume you are using negative planes with splits or you have an
attribute assigned that allows those nets to short or the short is being
applied by a layer turned on in the artwork films that is not part of
your stackup. There are other situations that can cause shorting not
detected in Allegro but these are common ones. 
 
We use a third party CAM tool on all jobs before sending Gerber's out.
You might want to consider doing this on future designs. There are many
CAM tools out there that will allow you to perform netlist to Gerber
compares that are not too expensive.
 
Thanks
Tony Cosentino

Group, I sent gerbers out and board house pointed out nets were shorted
to plane. I ran DRC and I didn't have nets shorted errors, this
shouldn't be.
