KiCad 7.0.8: Footprint does not match copy in library

Layout
1

In the layout editor 7.0.8, I get warnings like this:
“Warning: Footprint xxx does not match copy in library yyy”
if I deselect “Show” in the footprint Properties/3D Models.

That didn’t use to be the case, but I cannot tell for sure on which version the problem appeared.

If you modified anything in your project copy of the footprint, including the 3D model path then this is expected.

It’s not even the 3D model path, only the “show” option. While for most other options, I can understand the rationale, I don’t think it should issue a warning just because we have selectively decided not to show a given part on board in the 3D view while having modified absolutely nothing in the footprint. While having a different 3D model itself could have an impact (so it’s nice to be warned), just deciding to show it or not? I’m failing to see how useful that could be, except possibly for so niche cases that it’s not worth the trouble.

But I’m assuming no one bothered to handle this as a particular case, as I guess the “show” option is an integral part of the footprint characteristics that ERC will check.

So I suppose my remark/“report” has little chance of going anywhere. Thanks for having read. =)

Yeah there are bigger fish, er bugs, to fry. Just restore the library copy, put your copy in your personal library, or suppress that warning, if bothers you.

This is fixed in the nightlies (7.99).

We actually decided that it doesn’t make sense to check the 3D models at all.

Ok, thanks!

Well, to be fair, checking the 3D model itself could make sense, if you’re relying on it for mechanical
integration purposes and, say, a 3D model has been fixed and could impact your mechanical integration.

While my point was that checking the “Show” attribute itself seemed pretty pointless.
So, I would have kept the check for changed 3D models but would have ignored the “show” attribute, which is obviously an active decision of the user.

But just my 2 cents. It’ll be fine this way.
