Hi, did you try Shift+B after changing the outline? Otherwise you can click/select the copper area, then on the right side there should be a button for updating the copper area. If that doesn't work, save the work and restart the program? Hope that helps!

Thanks for your reply Mr.deskpro256 Shift+B works very well. Is there any Easyeda hotkeys in Easyeda documents Sir?

Great, glad I could help! There are loads more, you just need to see which are relevant for you to remember. Here is the list on the web: [https://docs.easyeda.com/en/Introduction/Shortcut-Keys/index.html](https://docs.easyeda.com/en/Introduction/Shortcut-Keys/index.html)<br> <br> And you can also find them in: Settings  > Shortcut Keys Setting and then you'll be able to change them or just look them up while in the EDA.  

Thanks for the link Sir
