Rigid Group does not keep Components together when making new Rigid joint

[kevsparky]

I have a screen recording of the issue attached. I have a Raspberry Pi model, with all components held together as a rigid group. I've imported that into a new project. Creating a Rigid joint only moves the component the joint is made with, not all of the other components in its rigid group.

I've tried this with many permutations, of where the rigid group is defined (in the current project or sub-project). I've tried importing the components directly, not linking to another project. I can't find a way to make it behave as expected. 

Does anyone know what the issue is?

Hi,

The joint is then completed when the process is "confirmed" with OK.

🙈 I feel a little stupid!
I know for a fact in the past that when you create a new joint, it animated the whole rigid group moving into place. This model has over 100 sub-components, so Fusion mustn't be animating all of them for efficiency. When the sub-components didn't all move into place with the PCB, I assumed it was an issue with the linking of the subcomponents to the main PCB component.
Thanks for catching the PEBCAK! 👍

I've been involved with Fusion since 2015 and can't remember any other behavior than the one described.

I've been directly involved in Fusion development since day 1.  I am almost certain that pre-OK joint animation always animated only the two components directly involved in the joint.  I know this because I was involved in the decision to do that.  It was done as a performance optimization.  Imagine if you had a very complex assembly with hundreds of components all connected with a complex system of joints, and it took, say, 20 seconds to show this animation...  So, to make the command preview more smooth, we decided to just animate the two direct components.
