overlapping copper - can not find the overlapping copper net
Nico
Hey Jeffrey G. Dumas! I think what's happening is that pin 24 on that connector is not actually connected to the portal. If you do what I did on the gif below, the drc error should go away

Nico - I redrew that net as you suggested and the design rule error cleared. But I still have the others shown in the image below - and redrawing the net did not clear them. It is very frustrating trying to clear these errors when it is not apparent where then come from. Also, please notice in the gif that you sent that the leads on the symbol for the connector are not quite in alignment with the nets that are connected to them. Is there a way too adjust the grid to make the symbol leads line up perfectly with the nets? Thanks for your help. Jeff

Hi Jeffrey G. Dumas: there seems to be a few pins that are connected to the wrong nets here. I've created a short video pointing them out: https://www.loom.com/share/219b7a150020414a92a688c7e7af6a82
I'm not 100% sure how the project got to this state, but my theory is that you had all your traces laid out, then removed the portals from the schematic and added them again. That causes nets to be re-created which means all the previous laid out traces will belong to a different net.

Nico - when you say "there are pins that are connected to the wrong nets " - if that is the condition of the layout, shouldn't there be airwires still visible? That is one thing that confuses me. Also - is there way to change the grid size so that the pins of the 32 pin connector line up better with the schematic nets? They are just a little out of alignment.

Jeffrey G. Dumas there should be airwires yeah, I'll create a separate bug report for that.
With regards to the pin's misalignment, those parts are created by the community, and the creator might've put the pins slightly in the wrong place. There are two ways of fixing it:
- Drop a comment on the part so the owner fixes it.
- Clone the part and fix it. If you go this route, I'd convert the part into a parametric symbol (https://docs.flux.ai/tutorials/working-with-symbols#parametric-symbols). That should make your life much easier.
Btw, if you have any questions on how to go about that, feel free to reach out to me at help@flux.ai or nicolas@flux.ai.

I'm trying to connect Net38 to the pin DRAIN4 (I think I have deleted all the existing nets to that pin). When I make contact to DRAIN4, that net becomes "Net40", even though it is just an extension of Net38 and then this gets flagged in the design rule check... (very frustrating). Also, I deleted short segment Net40 in the schematic, so that U1_14 is connected directly to pin 8 of J5. There should not even be a Net40 anymore.
