This newbie has a mysterious red cross. I’m sure I didn’t put it there, I can’t identify it, and I can’t get rid of it.
All I know is that it is not the same as an origin for drill files, which I did place nearby.
So what did I do?
Thank you
So what did I do?
I’m not entirely sure, but I think it is the origin point of a footprint. THT footprints usually have pin 1 on top of the footprint origin, and then you just see a black hole at the footprint origin.
You can check this yourself with:
- Hover over a footprint and press [Ctrl + e] to load a footprint into the footprint editor.
- Footprint Editor / Place / Place the Footprint Anchor.
- Select a new location. Now the cross is on the location you clicked.
Thank you, it is clearly to do with that… I found it in the adjacent footprint and moved it. The result was that the footprint moved and the cross stayed where it is. I only have one of these crosses in the entire job but every footprint was cobbled by me and I guess I just missed them.
They don’t appear to do anything useful.
Each footprint has one, but as I wrote in my previous post, for THT footprints they are usually hidden inside the “black hole” of pin 1. For SMT footprints they are usually in the center of the footprint and you see them more often.
Euhm… Location of a footprint is quite important. That you see them outside of the “LCD” connector footprint is an error in the footprint. This can be a problem if you want to go to automated assembly, but I guess that is not important for you at this moment.
If you don’t want to see them, you can turn them off with PCB Editor / Appearance Manager / Objects / Anchors
OK, thanks. I now see that they are not unique to this footprint, it’s just that they stand out so much. I have now edited the footprint and relocated it on the board.
Once you start seeing things, you start seeing them everywhere.
