Multiple joints between two components

[tmostad]

I am having trouble trying to join two components in an assembly and it seems to stem from the way Fusion 360 wants to pick the location of the joint. I have a complex component that I want to be planar to another component on three sides. I can successfully apply two joints but cannot apply the 3rd joint. Fusion complians that "selected joint type will result in a conflict". I have a planar joint applied to the two outside faces of the connector body to the two outside edges of the PC board. Now I need to align the face outlined in red (pointed to by the arrow) to the top of the PC board. See attached picture. How do I do that?

Hello,

What you are trying to do should be possible without a conflict.  Just to confirm it looks like you are trying to position a component relative to another and keep it locked there or should it have movement?  If it needs to have movement using planar works great, but if your goal is to lock in the position of the second component and not allow any movement a rigid joint is going to be a better option.  You just need to align it into place ahead of time and leverage the as-built joint rigid command to lock it in place for you.  

If you are able to upload your model I can take a quick look at it and verify there isn't something else going on.  There are other ways to lock the two components together I might be able to recommend once i see your model.

If you want to you can share a public link to your model by going to the left side data panel, right clicking on your design and choosing share public link.  That link will allow me to download the file if you so choose so that I can take a look on my end as well. 🙂

Possible, yes. But very unpratical for PCB desing. I'll record a screencast of how I'd do it 😉

Thanks for the link, I have included a screencast below of what I did to get it to work for me by back tracking before you made your joints and starting over.

The first way I should leveraging the planar joint command, again the planar joint works great if you are looking to have the component moving in the future.

The second way is leveraging the rigid as-built joint which locks the joint into position.  This joint won't allow any movement.  Since it looks like this is a PCB I suspect you are looking to lock in the position of the component, the second way is your best bet.  An alternate way to do this, but it takes some more setup which I haven't shown here is to create a Joint Origin on the PCB and define the distance away from the corner that Joint Origin is.  You can there use a rigid joint without having to align it ahead of time and any changes to the locaiton of the Joint Origin will update the position of the second component.

Hope this helps and if you have any follow up questions please let me know.

Dang. That was fast!

Thanks Joel! I was trying to do what you did except I guess I had an action in my timeline that caused a conflict. I am new to the timeline concept. I have used SW and Geomagic Design and haven't yet switched to the Fusion 360 paradigm. Thanks again for the top-notch help!

I am not using Fusion for PCB design. I need a 3D model of my PCB design so I can mill a cavity for a mold. I am using Fusion for that and I will use CAM to mill the mold which will be potted. I did this many times with SW. Still learning Fusion.
