    Re: Altium Width Rule Issue

    You can consider making rules that are applicable for specific devices only, with the Query Builder feature available either on Schematic or PCB scopes. The `PartDesignator` parameter is one candidate parameter if you want select by device designator ( e.g "U1" ), althought I prefer the `CurrentFootprint`( e.g "QFN-100-M" ) which would not be affected by re-annotation. It is not a straightfoward functionality, so it is advisable to make many experiments on your own to get fammiliar with it.
