[SOLVED] Some of the connections end with an empty square and some not

[LM21]

I wonder why some of the connections end with an empty square and some not, and does it matter.
This should explain this better

The bottom are unconnected wires.
Are the top examples green graphic lines?

They are alll wires, if that is what you are asking.

@jmk

The bottom are unconnected wires.

That maybe it in a theory, but not in real life, because:

[Claudio.Lorini]

The squares disappear if you make the square on the label coincide with the square in the extremity of the wire. it creates a ‘dot connection’ otherwise (visible when you try to move the label).
It’s the intended behavior and the connectivity is ok in both cases.

[Dmc]

Temporarily move one of each label away into an empty area… with the labels not touching a wire I expect you’ll see one is “left facing” and the other “right facing”. Use “r” or “x” to change that (so that the standalone labels’ empty square boxes are on the left side), move them back onto their wires and I expect things will be as you expect and desire?

An upvote for Claudio.Lorini. When the attachment point of a label coincides with the endpoint of a wire both squares are removed.

Open wire ends are also harmless. Even ERC does not give a warning for them, as long as the label is attached properly. The important part is that you do NOT see the square on the label. When the square of the label is gone, then KiCad recognizes the label is attached to the wire.

Also, you do not even have to draw the wire. You can for example first place the (attachment point of) the label on top of the pin, and then drag the label sideways. And you can rotate and mirror labels depending on whether you want the label starting at the end of the wire, or if you want the wire to continue over the baseline of the label.

Another simple trick is to duplicate (with [Ctrl + D]) both the label and the wire. This is useful if you want wires with the same length. And during duplication you can also rotate and mirror a block with multiple labels. And there are plenty of other little tricks in KiCad you will learn as you get more experience.

Thanks for all you for answers. I think I’d have try them to understand what you saying. But the most important thing is that my boards have worked and that there are no bugs

[paulvdh]

If you consider it solved, then make a habit to select one of the answers as the solution. This improves the forum usability for people searching the forum because it guides them directly to the solution without having to read the other posts. This is a new feature and you can do this with the little square with check mark at the bottom of each post.

A good idea. But now, I can’t tell answers apart. There seems to be several good answers.

@Dmc has the right answer, I’m pretty sure.

A label can be “facing” different directions and flipped/rotated around. It has a connection point at one corner, and depending on whether that corner is on the left or right of the label text, it will make a connection with the wire on the left or the right.

Either side will work, but if it makes a connection on the right, that connection will be in the “middle” of the wire. This will leave the endpoint of the wire showing as unconnected, because the label isn’t connected there.
