When manually adding tracks, the yellow lines indicating expected pad-to-pad connections do go away if you connect up as per, but do not disappear if you go from pad to existing track even though the connection is correct. Also, those yellow lines do not come back if you delete the tracking. Why is this? Is there a menu setting I've missed somewhere?

Tools =>Integrity Check will bring back the yellow "net" connection (if you have a Project with a Schematic).

You are deleting the net as well as the track when you use delete. Use Ctrl-U to remove a segment of track without deleting the net connection.

Ah ok, points taken, thanks, but that doesn't explain why the yellow "net" connections don't go away when a perfectly legitimate, but not direct, track is added?

I can see that the delete function as-is can be useful but it does seem dangerous too, particularly where the design is specified by schematics and to my mind really should be controlled by them. Either way though, surely it would be better if the slightly more radical operation of obliterating the net and also removing the net-pad associations completely was the less easy, multi-button task?

In answer to your first comment, try Tools=>Optimise Nets after manually routing tracks correctly terminating on the pad centres.
(perfectly legitimate, but not direct???).

With regard to your second point, there has already been a lot of discussion on this issue on the Forum, -and I'm not going to get drawn in,- I can see the logic in both methodologies. As long as you use "Integrity Check" and "Design Rules" properly before generating plots you WILL be OK.

If when you make the track you click on the "yellow" net connection, then the yellow line will disappear.

Note the delete net function can be turned off, settings /preferences PCB interaction /delete/ delete track does unroute, this I think was added to version 15 after much comments on this forum.

Ok perhaps I haven't explained myself properly (wouldn't be the first time!) - this is not about hitting the pad centre. If you have three or more component pads to track together, the temptation is to track 1st pad to 2nd, then 2nd to third, as per the yellow lines, and doing this removes the yellow lines. However, if you track 1st pad to 2nd, then track the 3rd pad to the track between 1st and 2nd, then that yellow line does not go away, and btw the track does not end up with the purple "I'm not connected" stripe down it so it is valid. I tend to track this way particularly on prototype boards so that individual pads can be cut free from the net for rewiring if necessary.

As for the other point, I didn't spot the previous discussions so I guess it is how it is.

BTW thanks Rob, box checked!
