Fixing PCB Overlapping Copper Errors

flux

Here’s how to resolve the overlapping-copper errors flagged by DRC in your PCB layout:
  1. Inspect each error in the DRC panel
    • Open the DRC view on the right-hand side.
    • Click on an “Overlapping Copper” entry to zoom to that location on the board.
  2. Identify the conflict
    • You’ll see two copper objects (traces, pads or pours) occupying the same space.
    • Check if they belong to the same net (OK to merge) or different nets (short risk).
  3. Fix same-net overlaps
    • If both copper objects are on the same net, simply union them:
      • Select one copper shape and use Merge (right-click ▶ Merge Fills/Traces).
      • Or delete the redundant segment so only one continuous copper remains.
  4. Fix different-net overlaps
    • If they’re on different nets, you must create clearance:
      • Move one of the traces/pads away using M ▶ Move so they no longer overlap.
      • Or change one trace’s layer via E ▶ Layer and reroute on a different copper plane.
      • For copper pours, adjust the pour’s Thermal & Clearance settings so it automatically leaves a clearance around the conflicting copper.
  5. Re-run DRC to verify
    • After making changes, click Re-run DRC in the review panel to confirm that all overlapping-copper errors are cleared.
  6. (Optional) Tune design rules
    • If you frequently see minor overlaps, consider increasing your clearance rule:
      1. Go to Design Rules ▶ Clearance.
      2. Raise the minimum clearance (e.g., from 6 mil to 8 mil).
      3. Refill zones and reroute traces as needed.
Following these steps should eliminate all “Overlapping Copper” violations. Once cleared, re-run the full DRC to ensure no other errors remain.

how can I remove all the silk shapes

flux

I wasn’t able to find any documentation on a one-click command to strip out all silkscreen shapes. It looks like Flux doesn’t currently offer a global “remove all silk” feature.
For more detail or to request this capability, you can check the Flux docs or join the Flux community:
