I can't understand your design. because this is a public project, so I link the gerber file to here. 1. can you check if your PCB design match your gerber https://gerber-viewer.easyeda.com/showcase/#!id=0af35973436e11e79ed5026a86b9cae7&type=top&layer_list=1-2-3-4-5 I need to know if the PCB house problem or the PCB editor bug 2. If not match, can you give me your PCB image and point where is the problem( the miss track)

#### The problem here is that: the missing ratlines and therefore routing is caused because the pins of the LED PCB footprints are numbered `1` and `2` whilst the **PCB pins** in the schematic LED symbols are called `A` and `K`. #### The solution to this problem is: If you EITHER: edit the pins on the PCB footprint to `A` and `K` OR: edit the pins on the schematic symbol to `1` and `2` and then do **Update PCB...** in the Schematic Editor or **Import Changes...** in the PCB Editor, the missing connections should appear as Ratlines. Then you can complete the routing. ### The BUG here is that if you already have an existing PCB design and then you do **Update PCB...** in the Schematic Editor or **Import Changes...** in the PCB Editor, *you do not get an* **Invalid Package** *warning* but: if you try to create the new PCB from the same schematic using **Convert Project to PCB...** *then you do get the* **Invalid Package** *warning*: ![enter image description here][1] [1]: /editor/20170609/593a81526f308.png

Hi Thanks, Support: The Gerber will match the PCB. The problem was that the LEDs were left floating during the PCB Update. A previous (manufactured) PCB was fine but this version was not. Andyfierman: Yes you are right. I realised if I delete the LEDs and redid them it would fix it up. The puzzle was that the last time I had the board manufactured it was fine but a few months later it was not (the package data has changed?). I also realise that I should have paid more attention to the Update not clearing after the PCB had been routed. Although at the time I did not realise I should check if Updates had cleared or understand why the Updates may not clear after routing. Okay thanks again, regards Alan@support

All fixed, deleted the LEDs in the PCB and the Schematic. Replaced with "new" version of the 3mm LED. Completed the PCB, rerun Update, it showed no updates are required. I will have to do this is any of my old projects that use LEDs. The fault is that the 3mm LED packaging has changed. Regards AlanC
