Fixing PCB Overlapping Copper Errors
Thought for 42 sec
Here’s how to resolve the overlapping-copper errors flagged by DRC in your PCB layout:
-
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.
-
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).
-
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.
- Select one copper shape and use
- If both copper objects are on the same net, simply union them:
-
Fix different-net overlaps
- If they’re on different nets, you must create clearance:
- Move one of the traces/pads away using
M▶Moveso they no longer overlap. - Or change one trace’s layer via
E▶Layerand 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.
- Move one of the traces/pads away using
- If they’re on different nets, you must create clearance:
-
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.
-
(Optional) Tune design rules
- If you frequently see minor overlaps, consider increasing your clearance rule:
- Go to Design Rules ▶ Clearance.
- Raise the minimum clearance (e.g., from 6 mil to 8 mil).
- Refill zones and reroute traces as needed.
- If you frequently see minor overlaps, consider increasing your clearance rule:
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

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.
