    Acid traps - you need to set the same net spacing rules up for pad to line etc, make sure they are enabled to DRC in two places, Setup - Constraints - Modes - same net spacing spacing and also in Constraint Manager - same net spacing - Options, turn to True.

    For the silkscreen over pads there's a skill file called silk utils (Dave Elder one) available on the skill forum.

    Hey Guys,

    I'm also interested on this silkscreen check over pads. However, I think the 'silkutils' skill available would only check if the pad or via has soldermask on it. What if mask is not present? Any other checking method or skill on this case?...

    Thanks!
