How to get a DRC error for a via in pad

Layout
1

Hi, on a layout I’ve made a mistake to have a via inside a SMD pad.
I’m surprised that this mistake has not triggered any DRC error.
is there a way to activa a DRC checking for that ?

The via and the pad share the same net, so it’s not a DRC error.

In 6.99/7.0 you can use the new mechanical_hole_clearance constraint to make this a violation.

In fact, the example in the syntax help is for exactly this situation:

    # Prevent solder wicking from SMD pads
    (rule holes_in_pads
        (constraint mechanical_hole_clearance (min 0.2mm))
        (condition "B.Pad_Type == 'SMD'"))
