Altium Designer 19 错误警告 Design contains shelved or modified (but not repoured) polygons

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。
