Concentric Joints in Fusion 360

Anonymous — Sat, 11 May 2019 23:01:21 GMT

I am having the most frustrating time figuring out how to constrain assemblies in fusion 360. I usually use NX 11, (far more intuitive software) however have to use 360 on my mac. Im trying to constrain a cylinder around another cylinder, then constrain holes in each cylinder to be concentric, NOT touching. Its so frustrating because I don't want to deal with offsetting joints to make the holes line up. Totally unnecessary. Image is attached. In addition, how can I constrain 3 faces on object to other? I don't want to use the points on the objects and have to line them up, should be able to constrain the bottom, then the side, then back. Right now, the servo is constrained on one side and I offset it to be where I want it, however it's not flush and is a hassle. Any help is appreciated.

I don't want to use the points on the objects, Sorry Fusion Joints work on common points between two components.

I would joint this to the common points, at this corner.

Might help....

You'd use two cylindrical joints for that. The joints in Fusion 360 works somewhat differently than the geometric mates in other software systems. Here is a link to a Autodesk University class recording that explains the joint system.

Thank you for this detailed solution!
