This tutorial will cover how to generate Gerber files to get a PCB that you designed fabricated using Altium Designer
Create an OutJob File
OutJob files are a type of file in Altium that allow designers to easily and repeatedly generate outputs from their design. It is very configurable and can group different outputs into one container so they can all be generated with one click. More can be read about it here on Altium's docs: https://www.altium.com/documentation/altium-designer/streamlining-generation-of-manufacturing-data-with-output-jobs
You can create an OutJob file by right clicking on the project in the Projects panel and navigating through "Add New to Project" > "Output Job File" as shown below
Creating Fabrication Outputs
There are two types of files we need to create, Gerbers and NC Drill files. The gerber files define each layer of the board and the NC Drill files define all of the holes that need to be drilled. Combining them gives the fabricator the necessary information to create your PCB.
Gerber Files
Under "Fabrication Outputs", select "Add New Fabrication Output" and choose \[PCB Document] under the "Gerber Files" option. This will add a fabrication output for Gerber files corresponding to the PCB document in your project. If you have more than one PCB document, select the one you want to make Gerbers for from the menu.
Next, double click on the newly created output:
