Latest update: Joint linked assembly

PinRudolf — Tue, 02 Mar 2021 10:53:17 GMT

Hi,

When I use a joint on a linked assembly the joint can pull one component to the new place. I would prefer it to move the full assemly to the new place. Arguably you could say the original assembly needs to be fully constrained if you want to do this, however a assembly like a 3D PCB does not give joint functionalities.

Currently, when moving a PCB with Joint, only one layer of the PCB will move. It did not do this before.

The workaround is simple; in de main assembly select the PCB component using the browser, then make it a rigid group. (Assemble > Rigid Group)

It is rather unfortunate I will need to do this to all PCB's. If the current bahaviour is by design, could the 3D PCB then be created as a rigid group by standard?

Also notice all previous projects have to deal with this new implementation. So all PCB's that are placed using joints are now out of place. (Well, most layers anyway.)

Kind regards

Pretty sure that nothing has changed in months, if not longer, in this area. This has always been the case in Fusion. All sub-assemblies are inherently not "rigid". And yes, the way to make this work is to create a rigid group of the entire PCB assembly

Hi Jeff,

Thanks for your reply! You are right of course, it has been like that for sub-assemblies! (Working with both Fusion and Inventor I mix them up, sorry!)

What's more, the issue on the PCB not moving doesn't show on all PCB's! It only a specific design I have problems with. I'll need to test if I can reproduce this with a new design. Will get back to you!

Hi Jeff,

This behaviour does occur on previously created boards, all board created before the last update. I could not reproduce the issue with any new boards though.

Faulted behaviour on a previous design:

Correct behaviour on a new design:
