Project Planning Guidance

Creating a personal project & new to fusion. Thought I needed 3 components, now realizing that joints require separate components to work, so I need 5:

Orientation:

• 1 is a moving "part" of 2.
• 2 fits inside of 3
• 3 magnet attaches to 4
• 4 slides in and out of 5 (with a screw to fix once it's at the required length)

I tried creating a new component and dragging the bodies/sketches to it, but it leaves the timeline steps with the old component.

1. Is there a clean way to move things around?

2. If I can't move around, do I need to restart or do I just not use joints for this one?

3. Any good videos on component / orientation planning? Some of my parts are meant to fit inside of each other, and I'm drawing them facing each other, which is proving to be a pain in the arse rotating/aligning. Guidance would be appreciated!
