How to deal with issues like this: **Set the copper area order in the Copper Area Manager. The upper copper has high priority。** [**https://docs.easyeda.com/en/PCB/Copper-Pour/index.html#Copper-Area-Manager**](https://docs.easyeda.com/en/PCB/Copper-Pour/index.html#Copper-Area-Manager) Two tracks. One GND, one VCC. Create outer GND Copper Area first.  Correctly fills and clears VCC track.  Set Copper Area to Invisible. Create inner VCC Copper Area just around VCC track.  Automatically rebuilds copper (or do SHIFT+B to rebuild copper) areas. All seems OK.  Set Copper Area to visible. Oops!  * **No DRC errors!**  Now do the same thing the other way round. Created the inner VCC Copper Area first.  Then add the outer GND Copper Area. This fills correctly.
