What are these dots / traces on my PCB?

I’m making boards and such, but when completed I get extraneous dots which appear to be trace elements but are not connected to anything. They do not appear in the board editor and there is nothing in my schematic for them.

ps: Yes they show up on the actual printed board when I receive them from the factory.

Hi,
hmm yes they look like trace segments. Maybe they are a leftover from editing traces? Theoretically there could also be some disconnected traces in the board after disconnecting nets in the schematic editor (though normally those are not that short segments).

How does it look in the 2D view? Couldn’t you just select & delete those segments?

And does the DRC warn about them?

I suspect they are left behind after editing traces, but they do not appear in the 2D board editor for me to select and delete. Yes, the DRC warns about them and shows air wire connections but again there is nothing in the board editor. The air wire shows an empty space. Here is one example but there are many. I am just ignoring them at the moment. (EDIT: Hmmm, I cannot upload images to the discussion, not sure why. But imagine a yellow air wire with nothing at either end. When I go in to 3D view there are these mysterious dots where the ends of the air wired indicated an issue during DRC.)

Ohh that should not happen. I just tried to reproduce it and indeed, traces with zero length are not rendered :sob: That’s a strange bug I’ve never heard of yet. Will open an issue to get it fixed in the next release.

In my test I was able to select those invisible traces with the rubberband selection. The selected zero-length trace is not visible, but if you press delete it disappears anyway. So I think you have to do it this way for now.

Thanks for reporting this problem :sparkles:
