The two main commands for bending sheet metal in Fusion 360 are the Flange command and the Bend command. Each has its uses but for precision bending of sheet metal the Flange tool makes the task a lot simpler. It will use the sheet metal rules, of the assigned material, and automatically calculate the bend allowances to create accurate dimensional bends. The Bend command can also make bends but you are required to calculate the bend allowances manually. In the video I reference a bend allowance calculator called Bendworks. This tool is no longer supported and updated but still functions of this tedious task. I will post a link in the comments.
If you have a choice, select the Flange command and finish your dimensional sheet metal design quickly.
