Remove overlapping vias

After a decade of using Allegro at a PADS company (translation causes 2 to 30 vias to be coincident.  Horrifying), I owe DavidE coffee and a steak dinner.   The skill utility can be found in this thread along with a discussion of how to deploy it.

 RE: detecting duplicated vias 

Hello all, it looks like you could do with a check for such mistakes... never fear, I got you covered! 

So there is a check for duplicate overlapping vias in the form of duplicate drill hole checks. 

I just retested this here to be sure. 

Please open the Analysis Modes form and in General checks you find it as shown below;  

On a demo design I snapped two through-hole gnd vias in an overlap scenario shown below.

Please note you will make the DRC flag visible using the "through" drc category. 

Hope this helps!
