Joint origin leaving component when creating joint.

[valerio.galieni]

I'm trying to create a fixed joint with a specific alignment between two components. I've created one point on each of the two components, that I would like to be aligned by the joint. However, when I create the joint, instead of the component moving from its original position to its destination, it is the point within the component that moves.
 
Can someone suggest a solution, or a different workflow to obtain the same result? Thanks!

you have activated a sub-assembly when you placed the point:

So, as a result, the new point belongs to that sub-assembly:

so, when you create a joint to this point, only the sub-assembly will move.  This does not move any of the child components of the sub-assembly.  

To get this to work, the usual way is to put the point inside a lower-level component.  If the rest of the components are then joined to that one, everything should move together.

There are other ways to do this, which involve creating a rigid joint between child components and the parent sub-assembly origin, so that the sub-assembly all moves as a group.
