PCB Net Routing Assistance

Diagnostic confirmed: the L2/L3 zones have copper geometry but are missing net assignments (effectiveNetId is null), so DRC treats them as decorative copper, not net-bound planes.

Fix in two steps:

STEP 1 — Create missing zones with explicit net assignment

The L2 GND zone and L3 3V0 dominant zone do not exist as proper queryable nodes. Create them now:

a) L2 GND PLANE

Layer: Mid-Layer 1 (L2)
Net: GND (assign explicitly — set effectiveNetId / net property)
Shape: circle, diameter 57.4mm, centred at (0, 0) — slightly smaller than the 58mm board outline to maintain 0.3mm edge clearance
Fill type: solid copper pour
Connection style: thermal relief to net-matching pads
Thermal relief: 4 spokes, 0.4mm spoke width, 0.3mm clearance
Stitching density: 2mm

b) L3 3V0 DOMINANT POUR

Layer: Mid-Layer 2 (L3)
Net: 3V0 (assign explicitly)
Shape: circle, diameter 57.4mm, centred at (0, 0), MINUS the two existing island regions (VSYS and 1V8_SGP41) — i.e., the 3V0 pour fills L3 everywhere EXCEPT inside the islands
Fill type: solid copper pour
Connection: thermal relief, same parameters as L2

STEP 2 — Assign net to existing islands

The L3 VSYS and L3 1V8_SGP41 island zones exist but have no net assignment. Set them now:

c) L3 VSYS ISLAND

Existing zone at (10, 18), 10×12mm
Net: VSYS (assign explicitly — currently has no effectiveNetId)

d) L3 1V8_SGP41 ISLAND

Existing zone at (-10, 22), 8×8mm
Net: 1V8_SGP41 (assign explicitly)

After Step 1 and Step 2:

Force a pour rebuild / fill regeneration on all 4 zones
Verify each zone now reports a valid effectiveNetId matching its intended net
Re-run DRC and report:
- New total airwire count
- Specifically the GND, 3V0, VSYS, 1V8_SGP41 airwire counts
- Render each layer (L1, L2, L3, L4) separately so I can verify the copper fills look correct

Expected result: airwire count should drop dramatically (from 170 to under 30), because most of the GND/3V0/VSYS airwires resolve through the now-net-bound planes.

If after this the count is still > 50, do NOT iterate further. Report back and stop. I'll handle the next decision from outside Flux.

Thought for a moment

I’ll attempt the four-zone net binding exactly as specified, then verify DRC and layer rendering. First I’m checking whether the layout editor exposes net assignment for copper pours; if it does, I’ll apply the plane fixes and validate immediately.

3/3 tasks completed.

Thought for a moment

Blocked: I can’t complete this safely because the current layout controls do not expose any editable net/effectiveNetId/net-name property for zones. I verified that connectedLayers, shape, stitching, and thermal-style rules exist, but net, Net Name, and effectiveNetId are not valid editable zone rules.

I did not create more decorative copper, because that would repeat the same failure mode. The next decision needs to happen outside this interface: bind the copper pours to nets in the PCB editor/API, then rerun DRC and layer renders.
