Instances of the same component have child components in different positions.

I think I've run into this in more than once. Maybe I don't understand how fusion handles components fully yet, after using it for a whole year? It's not behaving as I expect it should.

I have 2 components and one is just a copy of the other. I've then changed around part positioning and such on number 1 but it doesn't update on component 2 even after capturing positions on component 1.

Also these 2 components are children of another parent component

As I understand components (and comparing them to assemblies or models from other 3D modeling packages) If one is just a copy of the other one and not a "New copy" they should be exactly the same right?

Even when child components get moved in one, they should change their position in the other.

This is not happening right now.

Here's a better picture of the issue

This is something that is a bit different from some other CAD systems.  In a lot of other CAD products, sub-assemblies are "rigid" by default.  Meaning, that every instance of a sub-assembly show its children in the same position.  For example, if you have a sub-assembly of a door frame plus a door, and you have multiple instances of those in your building assembly, all doors must either be open or closed.  You cannot have one door open and another closed.  In Fusion, all assemblies are "flexible", meaning that you can have one door open and another door closed.  So, you should not expect sub-assemblies to all be identical. 

You can get to this state by fully constraining (as a rigid group, or with rigid joints) the sub-assembly.  Then, all instances will always be in exactly the same position.

I guess I'm just used to how the 8 or so other 3D modeling programs that I've used handle instancing then...
