Logic Need recommend the "intelligent" file formats like Gerber X2 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 Gerber/Excellon Files".
2-	In the "CADCAM (Gerber and Excellon ) Output " dialog, in the "CADCAM 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 "ok" button the process of generating the output file will start, and the program status bar will display the producing progress as shown below.
4-	The Gerber X2 files will be exported and  archived in a single ZIP file to the location defined in the Folder Path field. Find the archive (ZIP) file. And it is now ready to upload it to Logic Need. The ZIP file will contain the following files: Now, you are done. (We recommend that you give the files a quick check using any Gerber viewer software or online Gerber Viewer before confirming the order)
