Getting DRC errors with nothing showing
775 7

The DRC errors might be that traces are routed to the center of the pads, so there is a dot at the end of the trace, and it is dead center inside the pads.  I'm not sure about this, but the next issue could be the transformer I use , it was  put in the library with no holes, so i add the holes, and the traces route to the center of the hole, instead of to the edge. Maybe this is not the problem either.   I need some expert help, as the board is all done, and i want to generate a gerber file so i  can print it and check components  on the image. Easy to see DRC errors are easy to fix, but when you don't get anything listed, only DRC error, it is difficult to figure out. The board is not complicated, and i use the autorouter locally, and it runs fast and finishes in a second ot two. My feeling is that if the trace ends up inside the pad hole of a part, it should not be a big deal since the pad will get drilled, and any copper inside the pad will be removed. My guess is that the autorouter doesn't take that into consideration,   Any help on this will be appreciated. Joe

Hi You can check the DRC error via click the refresh icon at the design manager: ![image.png](//image.easyeda.com/pullimage/6NsyfnJtY141lsqLNQWIvIM8S4VG3ruTPQB4DcLS.png) at prensent, the editor doesn't support to check DRC from track to hole yet, we will support that soon Thanks

@Joseph Massimino, If this is the project you are asking about: [https://easyeda.com/joe.massimino/interface-board-modified](https://easyeda.com/joe.massimino/interface-board-modified) which PCB is it?

I tried to share it, but the only choice I had was cancel, I'm not sure what was going on. It did warm me that I was going to share it, but nothing happened.  I did  generate gerber files and looked at the board with the Gerber viewer, and it looked ok.   I won't submit it because of the box of boards they made that were garbage.  i keep them as a reminder to be absolutely sure before I submit for manufacturer. DRC appears to the left, but there is nothing listed under it, so that is puzzling. If I cross two wires DRC will show it in the list, but  it shows nothing, and on close examination, I can't see anything. I am stuck.

Is this the project you are asking about: [https://easyeda.com/joe.massimino/interface-board-modified](https://easyeda.com/joe.massimino/interface-board-modified) ? If yes then just say which pcb it is in that project. If it is a different project then see: [https://docs.easyeda.com/en/Introduction/Share-to-Public/index.html](https://docs.easyeda.com/en/Introduction/Share-to-Public/index.html) ![image.png](//image.easyeda.com/pullimage/dqutl45MKtMDFMUKQeTbtHmx5jJ7HHDuZI7oS6i7.png) OR: Download a copy of the **Project** as a json file: ![image.png](//image.easyeda.com/pullimage/Dfw9WL0ItGQGtgKyo4QSNavX8uYdY5O946Wcb9xv.png) Email it to support and tell them which pcb it is you are asking about.

@Joseph Massimino, "The DRC errors might be that traces are routed to the center of the pads, so there is a dot at the end of the trace, and it is dead center inside the pads.  I'm not sure about this, but the next issue could be the transformer I use , it was  put in the library with no holes, so i add the holes, and the traces route to the center of the hole, instead of to the edge. Maybe this is not the problem either." * Tracks are supposed to snap to the centres of pads. I have looked at your PCB and I can find no DRC errors. There is one track unconnected: ![image.png](//image.easyeda.com/pullimage/GyxMglNZ6ba9DGt08Jd0094PwcVC8t6hWlfprz5A.png) and some that are strangely tracked: ![image.png](//image.easyeda.com/pullimage/bpPq6AqhAVoRIKhJ3kauU61ukASugbUlbwwT74De.png) ![image.png](//image.easyeda.com/pullimage/T64ZmdHNLED3TLPyBRMGVsJ7K1rI6hsKCYecFNQg.png) ![image.png](//image.easyeda.com/pullimage/pxXyaAmcVu2rHYmhFUtApSzUca3AXtwNnODez3aR.png) ![image.png](//image.easyeda.com/pullimage/rgzR9wrTLrS2wLbeUkWgUCQ1INy4oTbzDpqisklJ.png) but besides those, I can see nothing obviously wrong with the PCB.

Thanks Andy, I went over every trace and took out anything that did not belong, and then i checked each connection and locked it once I saw it was connected properly. Then I produce Gerber files and got a good Gerber viewer and examined them against what I have in the EasyEDA files. It all looked good.  Then I sent the board to be made and examined them again. The EasyEDA software does not produce anything in the DRC list,  it only produced DRC error. I think they can fix the software to work better. I had to stop using the auto router and fix and lock each connection that was in error.  I have 800 boards being made, so I hope that it all looks like what I uploaded. I did put a note in the order about the DRC errors that don't actually list any errors, so I have no idea what caused it. The board I see when I view my Gerber files should be what I get. I have had too many problems that were my fault for not being as  persistent at examining the boards at every level, right up to the Gerber view that was given on the ordering screen.
