I previously used APD 15.XX and the balls from BGA could be deleted by going to the 'edit' -> 'BGA' however that option seems to have disappeared in 16.5
Can anyone please advise as to how I can go about deleting unwanted balls from the BGA? It's rather frustrating...
In 16.5, the Symbol Edit application mode replaces the old BGA and Die Editor commands.
To delete a pin, change to the Symbol Edit app mode (Setup -> Application Mode -> Symbol Edit or select it from the RMB Application Mode submenu). Ensure that pins are enabled in your find filter, then RMB on the BGA ball you want to delete, RMB and pick "delete".
