Logic Need recommend the "intelligent" file formats like ODB++ file format over the old formats (Gerber RS-274X artwork files / Excellon drilling files) to ensure superior manufacturability, quality, reliability and consistency.

1-	Open your PCB Design file on Proteus software, check integrity of the files. Here we used the file name "MyPCB" as an example file.  Select the menu "Output", then left-click "Generate ODB++ Database".
2-	In the "ODB++ Manufacturing Output" dialog, in the "ODB++ Output" tab follow and select the parameters as shown here: (We use a light-green colored blocks for marking the required selections)  In the Folder field select the location where the output file will be created
3-	After pressing "Generate" button the process of generating the output file will start, and the "Log" tab will display the generating progress as shown below.
4-	when the generation process is finished you will find  "odb++" ZIP archive file is exported to the location defined in the Folder Path field on the "ODB++ Output" tab of the dialog.   Locate the ZIP archive file to send it to Logic Need Now, you are done. (We recommend that you give the files a quick check using any ODB++  viewer software. To download ODB++ Free Viewers click here.  You will need to "join" the alliance in order to download the free viewer).
