Need help on understanding how to fully dimension a 3D sketch

Hello all, I'm just getting into 3D sketching and I'm facing a small problem. I'm trying to fully define this 3D sketch of a bicycle handlebar. I did try to define as many things as I can and I've also tried to see if I could move different parts of the sketch, to no avail which seems promising. Using fix/unfix on the handles fully defines the sketch but using it on the angled part of the bar or the strut only fully defines the areas connected to it while the handles still remain blue so I'm not sure what I'm missing so I'll appreciate any light shed on what I'm doing wrong.

Hi, Please, find below the steps I've used for fully constrain the 3D sketch and the file where I've done it.

@alessandro.gasso -my jaw dropped when I saw that a AD employee suggested to a new(ish) user using the fix constraint to make a "fully defined" sketch.  giving up all hope of parametric design are we? honestly, you should be ashamed of yourself.

 

@enkou_theflame  - there are ways to fully constrain this as a 3d  sketch using construction lines drawn on and from the original sketch plane, along with some dimensions.  BUT this particular sketch is planner, so it would be more stable and straight forward to establish a "plane at an angle" and put a 2d sketch on that instead.
