Thank you.

Hi, you can create as many electrical symbols as you want and associate a mechanical symbol.For the screw, create an electrical symbol yourself, add a connection PIN and associate it with the mounting hole. This way you can also give a signal to the screw

You are right, but I just didn't see the significance of that very short message, probably because it doesn't mention Schematic. screen.

In an email sent by meelis.reimets yesterday at 0415 it says "I have
mounting hole symbol in Mechanical library".

In this case, I think I can say NO. The Mounting hole library is only accessible from the PCB screen. The Mechanical library is accessible from the Schematic screen.

But that's exactly what both myself and others said to do in earlier
emails!?? To quote myself, "there are loads to choose from in the
Mounting Hole library".

Robert.

THAT'S IT!! That's the key fact I've been looking for. Use the Mechanical library.? Merci beaucoup and then some!

I now use my owne library, however I think I used a symbol of the mechanical library as example:

So, with the Schematic screen open, I look for symbols for mounting holes and I don't find them. Do you see that there is a single crucial piece of data missing? I'm beginning to deduce that they have to be added as pads, but until just now, I think that no-one has said so explicitly, and there is still a question whether that's the best, or the only, way to do it.

I'm sorry that we are not communicating I think you know so much about the subject that you can't see the silly problems a beginner has.

No, the first two sentences say it's about adding mounting holes to the
schematic.?? I don't know how I can make it any simpler.?? I explained
how to add a mounting hole to the schematic, how to optionally assign it
a part number for the screw, how to assign it a footprint (there are
loads to choose from in the Mounting Hole library, as others have said,
or you can make your own in a few seconds), and that you could
optionally connect it to, for example, chassis ground in the schematic.
?Now when you go to the board layout and tell it to update from the
schematic, like any other component your mounting hole will appear,
ready for you to place it.

And /if/ you export the BOM, it will appear in the BOM.?? You don't have
to export the BOM, but it sure makes ordering components easier,
especially if you have the part numbers in it for the correct screws.

Regards,

Robert.

just don't get the implications of what you wrote.

Unfortunately, the REF** is only a symptom of the real problem.

"But I see no way of changing the 'REF**' text for the mounting holes in the PCB."

"So you need to click on the component properties, and uncheck the "visible" flag on the "reference" field."

?

If it helps any, another way to switch the 'REF**'? 'visible' flag to 'off' is to hit 'Delete' after clicking on it.? Most projects do not need a RefDes label on the silk for mounting holes- especially if you are already tight for space.

?

Kind regards,

Brian
