Hi, you need to save the schematic to your project before you can convert it to a PCB. File > Save as > \- Check save to existing project \- Select the project you are working on \- Press Save and you're done\, you can now convert your schematic to a PCB\!  Good luck!

Hello ; Make sure that you save the schematic in the create project before converting to PCB. If this is a shared project, check the RW permission you have. Check the following guide for better understanding of the "Convert to PCB" topic : [https://docs.easyeda.com/en/Schematic/Convert-to-PCB/index.html](https://docs.easyeda.com/en/Schematic/Convert-to-PCB/index.html)

Cannot convert to PCB. Read: "the schematic has duplicate prefix of the components please make them unique". I checked the project 100500 times and found no repetitions. Thank you for the lost time, and negative experience

Your project is private so only you can see it. If you would like to make your project public and post the url to it,  others on this forum may be able to help you identify the cause of your warning message. In the meanwhile it may help you to read and follow the links in: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a)

@Angar15 You can check it at Design Manager

@Angar15, Note that all schematic sheets in a project will be converted to a single PCB. If you have more than one schematic sheet in a project then there must be no duplicate prefixes across all sheets.
