Hi, Can you clarify your question? You've said you are `...attempting to use the Arduino Shield schematic...`. and that you want to `...amend it by removing the 6 pin plug`. but what you have posted is some images of a PCB in which you are trying to delete the some PCB packages or footprints. * Your project is private so only you can see it hence some questions: 1. Is your PCB created from a schematic? 2. If yes, what schematic module have you used for the Arduino shield (can you post a screenshot of where it is in the SHIFT+F library search)? 3. If your PCB was not created from a schematic and has just been created by placing a PCB module into it, can you post a screenshot of where it is in the SHIFT+F library search? 4. If your PCB was not created from a schematic and you have not already, then you might like to read: https://easyeda.com/andyfierman/Welcome_to_EasyEDA-31e1288f882e49e582699b8eb7fe9b1f

@andyfierman I started with the item on the EDA start page as the basic schematic, modified it to remove the components from around the main card schematic symbol except for the reset cicuit elements, then saved it as a module. ![Selection from start and resultant schematic Lib module][1] [1]: /editor/20171116/5a0cb5e15cfcd.png I then converted the module schematic to PCB, and it's that that I can't modify, only delete completely. I'm starting to assume that's because it's become a "package" as the Arduino shield schematic symbol does not have one. I've tried deleting unwanted elements from the schematic symbol first too, but the same is true there, it's all or nothing. Perhaps I need to master amending public library schematic symbols? so far I've only created new ones or changed PCB footprints.
