Hello everyone,
I've just built a Cardan Joint, and I have to add an extension to the rotating pin at the bottom. The thing is that the pin at the bottom (inside red circle) is a cylinder, and thus can't grab the extension (marked with a red X). Therefore I would like to add a small box (inside blue circle) at the end of the pin, so it can fit into and grab the extension, and make the whole Joint rotate.
But how do I add this inside the assembly? I tried sketching it onto the cylinder from the bottom and then make an extruded boss/base, but the whole joint didn't rotate. Any simple way to do this?
You need to edit the part in the assembly and then add that square boss or cut. Finally you need to make them properly withe part on the bottom.
