Ratlines don't show while creating PCB

Hello experts! I'm new to EasyEDA and to PCB designing in general. I'm an electronics engineer though. I've been trying to make a PCB for a prototype I've been working for. I am using an ADE7763 Energy Meter SMD IC. I'm using an SSOP to DIP adapter to build the prototype board. Since the adapter board is not a standard component, 1\. I created a PCB Lib first and created 20 pads and spaced them as per the dimensions of the SSOP\-DIP adapter board pins\. \(image 1\) 2\. I then create a Schematic Lib with a box and 20 pins\. I ensure all pads and pins are mapped correctly \(image 2\) 3\. I then create a schematic and add the schematic lib of the adapter with few components to test \(image 3\) 4\. I create a PCB from the schematic When the PCB window opens up, I don't see any ratlines connected from the SSOP adapter to the other components (image 4). Am I doing something wrong here? Is there a way to export my schematic, schematic lib, pcb lib so that I can attach it here? Thanks a ton in advance for your help! ![image 1](//image.easyeda.com/pullimage/vzOwWGhiaX888fYc0T4Wp2u8ZINSBwBym1bZc4Bt.jpeg) ![image 2](//image.easyeda.com/pullimage/aBFZYkSCInPlhV92CGX6l2kcXlhbdK6qSEHawCVR.jpeg) ![image 3](//image.easyeda.com/pullimage/1BCG1vldBIBuq4OzedvkxUdCt5u1Fszp88K30dOT.jpeg) ![image 4](//image.easyeda.com/pullimage/bsRktKWVrsgK2fzfuJx1CHbBoWEhL7Gain7RixYt.jpeg)

Simple error. You have placed all the pins on your symbol the wrong way round. ![image.png](//image.easyeda.com/pullimage/AvZj6jc2FTxLHBtydEHikQFWayc3NGiECKbHbW3Q.png) The grey circles at the ends must be on the outside because they are the wire join nodes. Like this: ![image.png](//image.easyeda.com/pullimage/rBeOgq7AL51JavDDpWHJe2e1p9gh1NZ9sCAtypgB.png) See: [https://docs.easyeda.com/en/SchematicLib/SchLib-Create/index.html](https://docs.easyeda.com/en/SchematicLib/SchLib-Create/index.html) **To fix it:** Select all the pins down one side and then flip them left to right (left-click and left drag then press the X key. Rotate 180deg using the Space bar works too). Repeat for the pins down the other side. Realign if necessary. Save the symbol. Update the symbol in the schematic and save. **Update PCB...** or **Import Changes...** Save the updated PCB. :)

Thanks a ton! That indeed was the error. Have some queries that i wil post separately. This is a wonderful platform really.
