如遇到该问题
铺过铜或者未铺铜时运行DRC检查弹出该警告：
Design contains shelved or modified (but not repoured)polygons.
The result of DRC will not be correct.
Would you like to continue?
Note:recommended to stop DRC and restore/repour all polygons before proceeding with DRC.
运行完DRC后，出现错误警告：
Design contains shelved or modified (but not repoured) polygons. The result of DRC is not correct. Recommended to restore/repour all polygons and proceed with DRC again
Polygon named: Top Layer-GND 3 On Top Layer
Polygon named: Top Layer-No Net 1 On Top Layer
Polygon named: Top Layer-No Net On Top Layer
Polygon named: Top Layer-GND 1 On Top Layer
Polygon named: Top Layer-GND 2 On Top Layer
Polygon named: Abstract polygon ID On Top Layer
解决方案：
覆铜时分块覆铜，绕过板子四角焊盘孔。若覆铜后对板子又进行修改，则右击覆铜，选择Polygon Actions ->
Repour Modified,进行修改覆铜。
