So I found out. The hard way. Actually, my schematic is too wide for a single width of the drawing sheet, so I've had to wrap it into two rows, and the renumbering doesn't cope with that. Still, that is what learning is about. Such schematics should be numbered manually, or, once a year (That'll sort the old 'uns from the youngsters. Think 'toothbrush').

If you renumber everything then yes that will mess things up.

Why did you renumber?

There are various options the one you want is don't renumber anything
that is already there, just new things.

If you renumber everything then yes that will mess things up.

I don't know of any way to recover from such a mess

Rule 1 ALWAYS backup a project when making a major change. Is the best
you can say

disaster, other than not renumbering?

I have another question: is there a way of printing the list of keyboard
shortcuts? Since it is an HTML page in the on-line manual, I can't see
how to do it.

Place all units does work, but you have to be a little careful to avoid
"clickitis" :-)

in the circuit editor
add symbol

select switch / SW_DP3T

(here you can select either the entire unit, or each part, select the
entire unit SW_DP3T)

At the bottom of the selection window ensure that the place all units is
selected.

The next bit is where I think you might be going wrong

Select OK

the system is now ready to place the units. It will ONLY place one unit
at a time, not all in one go.

So move to where you want to place the first unit and click ONCE

Move to where you want the second unit and click ONCE

For a two unit symbol such as this that's it all done, but if it was a
4,6,8 or whatever part unit you would need to repeat the placements
until all done.

Get used to making your own footprints and symbols it's one of the most
useful things you can do as it's a great time saver.

The way to go is find a symbol (or footprint) that's close, copy it,
rename and save in your own libs which you should be doing anyway, and
it's not a good idea to use the provided libs directly as you have no way
of knowing if an update has changed something. It's should not, bit it
can happen.

But I can't find? a schematic symbol for it, only SPDT_MSM for a
single-pole version. Do I have to make a new symbol for it? That means
delving into the 'user libraries' process, which I find very confusing.

Actually, I am using only one pole, but that switch fits mechanically
very well and I have a supply.

Thanks, Robert, but I've already started again.

In the "Update PCB from schematic" tool in version 7, IIRC you just have
to *not* select "Re-link footprints to schematic symbols based on their
reference designators".?? If that doesn't work, you can also go around
all the components on the PCB manually giving each one the correct
designation, and then update the PCB with that box *selected*.?? I know
the latter works, because I partially did this last week (for completely
different reasons).

Regards,

Robert

No, Tony, I wouldn't dream of it. But I just forgot to save the schematic before going to bed at 0030.

You don't want to get me started about <users> making backups of anything valuable, do you?? ;-)? I think we've had that conversation before.

In KiCad 7 and 8, they are at C:\Users\[user]\AppData\Roaming\kicad\X.0\user.hotkeys, but the texts are barely readable by humans.

For the hotkeys, find where the KiCad configuration files are stored. I guess on Windows, it would be somewhere close to:

Thanks, Tony. I will investigate. It would be good to put those locations in the Manual.

It's 'Update the PCB from schematic' that causes the problem.? V8 seems quite a bit different from v6, and better, but driving lessons are required.

You should be able to 'feed forward' the changes. That should then renumber the component placements. I can't remember the appropriate commands at the moment, and I also haven't got around to playing with v8 yet (but hope to do so soon).
