I'm having an issue with the DRC rules.
My rules have a 7mil setting for via to via clearance
Measuring the distance between two vias shows it's defiantly less than 7mil. Using the measuring tool, see the white line.
But the DRC does not yell at me. "No Errors Found"
But, if I put the two vias even closer, the DRC does yell at me, but says the Rule is 5mil. Which means it's not using the via to via design rule, but the via to SMT rule? Which is 5mil
Is this intended? Or a bug?
Via To Via DRC
Re: Via To Via DRC
If I'm interpreting the help file correctly, one cause of the problem could be a "class-to-class" clearance setting issue. DipTrace states "...class-to-class clearances have higher priority than regular net class clearances...". You might want to check that out just to be sure...

Re: Via To Via DRC
You are absolutely right.
Both those NETs for those vias were under the same Net Class with 5mil clearance and the "Use Clearance in DRC" box was checked.
All is well now.
Thanks for the help.
