How to add sliding and rotating joints between pistons and cyliders?

[jomckissoc]

Hi, teaching myself Fusion and I ran into this issue. Building an air engine that has a set of pistons that both slide and rotate between two cylinders that are mounted at a 90 degree angle to each other. I'm stumped on how to join the piston to the cylinders so that when one cylinder rotates, the pistons slide and drive the other cylinder. I'd appreciate your help. Thanks!

I will send your model along in a minute but in a nutshell, you should not use a Slider joint for the piston to the cylinder.  You are forgetting that the Piston and Cylinder not only slide within each other but they ROTATE also.  You should be using a Cylindrical Joint instead of a slider.

I broke the links between your fasteners and the Model so I could send the file back to you as a F3D file.  DO NOT USE this file to continue.  Video will explain the post I gave earlier.  Model attached.

I placed all the pistons in place and added a name to the Joint to drive the assembly (Drive Me) and exported the model.  Again, do not use this one as all of the fasteners have been broken from their link.  It is just for demo.  Model attached.
