connecting a Signal to a via in board editor

reading the whole tread, especially your answer to Gary, I think I

understand now what you are trying to do but didn't state explicitly

anywhere 8-)

You've placed a part in the schematic and now you want to connect one

of its pins to a via you placed in the board, without this pin being

connected to any net in the schematic.

If that is the case you can't connect anything to that pin in the

board (as you already stated) because there is no net to connect to.

But you don't need a you pad as a part, just connect a short net stump

to the pin in the schematic (and give it a name if you like). Then

"via 'net-name'" (or placing the via and renaming it afterwards) gives

you a via connected to that pin.

You need to do a ratsnest to see the aitwire though.

Or ctrl-click to start routing on either the pin or the via.

I'm on 5.8 here, but I can't remember any change in behaviour in this

area since 4.x

On the other hand I prefer using a part because that documents the

precense of the via (test points in my case) in the schematic.

And placed as a part in the schematic I won't forget to place it in

the board.
