Purpose

A hole that is supposed to be isolated from power or ground planes must be kept apart from copper.

The distance that is required is typically larger than regular spacing due to the higher than usual current.

Function

Reports for drills embedded in laminate the distance from the edge of the drill to the nearest copper when less than the pp_d2c action parameter.

Activation

The ERF variable classify_via2c determines whether the system will distinguish between PTHs and vias.

Known Limitations

In Positive P&G layers no associated copper feature is reported.
