Rename existing floating wire segment in board

If a signal segment has the signal name of an existing net present in

in the schematic" message.

 

Now, if this segment was "floating", meaning it was not connected to any

of its target pins, or ending in airwires, why prevent this renaming? I

do support this "error" message when it is connected to one or more

target pins (although sometimes I would like to override it).

if I understand you correctly, you want to 'reuse' an already routed

track for a different net.

After the rename the original net then would have an air wire instead

of the track.

Correct. I am doing large designs and sometimes I find a long wire

segment already laid down is more suitable for a different signal, or I

simply want to swap two wire segments because it will ease routing.

I'm listening intently to this thread.  I've had this need on numerous

occasions.

Jorge?  Care to chime in?

Hi All,

I can't speak for the devs, but I think that they choose to err on the

side of caution and just completely forbid net renaming on the board.

In this particular case I'm having a hard time thinking of a good reason

for this behaviour. I think the risk would be that if the floating

segment has the same name as an existing net then renaming that segment

would rename the whole net.

The proper thing to do in this situation would be to have a dialog

similar to the polygon where you would have the options:

-rename only this segment

-rename entire net

Currently no such dialog is setup on the board side. I do think it is a

reasonable request, a few things in EAGLE would have to change though.

Best Regards,

Jorge Garcia

I see this as a valid concern. Especially when you edit a board alone.

For sch+brd consistant projects, renaming a net should be a sch only

feature, but I do see that would cause some inconsistancy and potential

backward compatibility ulp issues.

There are sexy ways around it, but that means you have to stop making

command line unfriendly and forced requesters (who decided to use that

in die hard command line based platform like Eagle anyway?). Do it, like

suggested in older posts, with optional command line arguments instead,

and you can keep all the default options legacy-like. This goes for all

the existing requesters too. (Yes I know you can use set confirm, but

that option is incomplete for a lot of the requests).

I would really like to see this feature too, and I think a dialog similar

to what you describe would be a good way to do it.

Hi Guys,

I have just filed an enhancement report for this one. Sorry I took so long.

Let me know if there's anything else I can do for you.

Best Regards,

Thanks Jorge.. I just found another issue that is closely related to

this issue.

The "rename oldname newname" command doesnt work for wires/nets in board

editor.

At least I would like this to be possible for nets not present in the

schematics, cause now I get told to do it in the schematic... where it's

not present.. Thats a bit funny..

I want to use this to rename pasted wires to whatever they are connected

to. As you know, pasted wires gets a new netname. Now I have to use

"name newname (x y)" to get to it, and that is not so nice, cause other

items may be at (x y) too, even at the same layer. Even hiding all the

other layers doesnt get around all cases.
