zone fill overfloods unconnected pad + chessboard pattern
Description
The provided board shows two issues regarding the zone fill:
- there is a irritating chessboard pattern
- one pad (which is not available as pin on the symbol) which should be unconnected is overflooded by copper
Luckily the DRC catches the unwantedly connected pad, so a false produced pcb could be avoided.
Steps to reproduce
- open attached project, open board: SEQU_One_v10_reduced.zip
- look at the zone fills (if you want you can recalculate, the zone fill result was always the same)
- note the chessboard pattern on the right (picture 2)
- more important: look at pad4 of AD8418. This IC was added twice.
- Pad4 - IC6 looks good
- Pad4 - IC5 is unwantedly connected to the gnd zone
