When creating sheetmetal we use threated rivets to mount the panels together to create the complete bodywork of our machines.
It's a shame that the joint function is not applicable on shapes that are identical like the example below. It's only good for round holes and points but thats not the case here.
You can also use rectangular/circular pattern to place them if the build-up allows this but in a lot of cases other component make this not possible and the position is therefore not always perfectly symmetrical.
With a joint this could be done with a few easy clicks now it has to be done with at least 2 constrains per rivet. Multiply this wit a couple of hundred rivets in your bodywork and you lose a lot of time and money.
