Two concentric holes on two components

[Anonymous]

So basically I have two components. Each component has two holes. These holes need to be concentric. How can I do this? I have tried joints, but only one joint is allowed. I have tried to align, but if I align one hole and then the other it moves the whole component. So frustrated right now I have been working on this all day long and made no progress at all.

Without a file or screencast,

Sounds like you tried everything.

Yeah I can't really post a screencast of this part, but all i want to do is line up two holes of two components. should be easy. should be..

This technique may work for you.  Add temporary rectangular features between the holes on each component. The rectangular features should be identical, but as long as they have a point in the same position relative to the holes, the align operation will work.  In the video I put the rectangular features in the components, but really all they need is to be a rigid group.

If this isn't the alignment you're looking for, post a simplified model.

Excellent work around, thank you for sharing this with me I really appreciate it. Maybe I will create a simplified model of what I want to do. In the mean time I will use your workaround since I know that will work for what I want. 

Thank you!

I think you could also use cylindrical joints and a motion link to accomplish the same alignment. You would need to create the shafts.

That is incorrect. Fusion 360 will warn you that a joint already exist between the two components but it will not prevent you from applying a second joint, which is exactly what you need in this case.

If the distance between these holes is exactly the same you can use two revolute joints. If not you may beed a revolute joint and a pin-slot joint or so. I've done this often enough but don't remember exact details. I do know, however, that that works.

You are right. One must use the correct "combination" of joints to achieve the desired result. The preview was throwing me off because it only shows the joint currently being selected. My fault. I thought I understood joints more than I do. I watched a 1 hour video by Lars and now I'm an expert.

Edit: In my defense, many of the combinations of joints that in ones mind could potentially work to get the desired result, in fact result in a conflict and ruin both joints.
