The "Airwires" review flagged a error on M3-3:terminal, M3-1:terminal.

Reports missing routed traces between pads in a net.

Designators: M3-3:terminal, M3-1:terminal; Net: CHASSIS_GND

Context: Reports missing routed traces between pads in a net.

Help me fix this. these are just mounting holes that can bonus as gounds but dont need to be

I’ll remove the mounting holes from the required CHASSIS_GND connectivity so they no longer create airwires. First I’ll verify the current net membership, then disconnect only M3-1 and M3-3 from CHASSIS_GND and re-run the airwire check.

The M3 airwire is cleared, but disconnecting the optional holes exposed schematic warnings because the mounting-hole pads are now intentionally unused. I’m cleaning that up by marking the mounting-hole terminals as no-connects so they won’t demand routing or generate floating/single-pin warnings.

Fixed. I removed the M3 mounting-hole terminals from CHASSIS_GND routing requirements and marked them as intentional no-connects, since they’re optional “bonus” chassis grounds.

Validation: the Airwires review is now clear for this issue, and the M3 mounting holes no longer show related floating/single-pin warnings.
