You might have seen that how to make a PCB, but before making PCB you must have knowledge about how to make layout for making PCB.

Why to create Gerber file? It’s because there are lots of software which are used to make layouts. I have told at start that OrCAD, KiCad, Eagle etc softwares are useful for making layouts. Fact is I use KiCad but many of manufacturers may use different software other than KiCad. So Gerber file is a file which will help manufacturer to know about your project and that manufacturer couldn’t make changes to the Gerber file. Now there are softwares which allow making changes to the Gerber file. Forget it we are just learner. We don’t have big budget project so it’s not mostly usable for individual. We can see gerber file by clicking on file>open and selecting any file which we have already created.
Manufacturer can see the following views like top view and bottom view
