Reference to a component that I moved later - sketch still shows component in original location

I am working on a model that contains several components. After I finished my model, I created a new version where I changed a few things. One change is that I moved 2 components 1 mm downwards (PCB and a upside down pushbutton).

As a result of this action, the bottom of the pushbutton, is colliding with the Housing (penetrates it for 1mm).

In my sketch to draw the bottom of the Housing, I referenced the bottom of the pushbutton. I projected the bottom of the pushbutton and used some colinear constraints as marked in below screenshot.

But now the pushbutton is 1 mm lower, but it looks like the bottom part of the Holder isn't correctly updated. No problem, I will just redo it. But the projection of the pushbutton still seems to use the previous position (1 mm higher). I can't even redo the projection, because the button is still at the original position when I edit the sketch. It means that the position of the pushbutton in the sketch is different as the real position in the model - it is as it "remembers" the original position, and doesn't show the new position. So I can't undo/redo the projection.

 

Question: Is there a way to kind of "update" the position of the pushbutton in the sketch, so that I can redo the projection, and re-reference bottom of it?

 

Attached you find the model.

I have had a look and maybe you can get what you want by dragging the moves to before the sketch in the timeline.

 

NOW..  I will say that moves are in general a bad thing to do, especially so in an in context assembly for reasons you are seeing.

Root problem, nothing is grounded.

Next problem, there are no joints.

Move with Capture Position is not recommended.

Capture Position, (temporary) make the Joint, and delete the temp Capture Position - is recommended.

Editing this sketch - marker here - Fusion doesn't know about the new Moves you have temporary cancelled while editing.

 

You had it correct the first time.  Delete / Suppress / Edit this capture position, (greyed out left of the sketch,) makes the sketch correct 3mm below the green frame, compared to the unnecessary moves at the end of the time line.

 

Might help.....

Thanks @carl.j.barker - it's indeed as simple as that. Although reading further below, I still have to learn more about the concepts of Fusion 360, but your solution solves my problem completely.

Thanks @davebYYPCU. One of the reasons that I have already made 3 versions of this model is that I try to do it better every time. There are still a lot of things I have to learn about the concepts in Fusion 360. Thanks to your answers, I again learned a lot!

I did ground... but much to late.

The more I'm working with Fusion 360, the more I learned that STRATEGY is important. I'm glad I didn't show you my first version - that was really disastrous 😁

About the joints, I did use them, but used RigidGroup. Although, this is something you can't do from the start, as all the components don't exist yet, right?

About the "move with capture position". To be honest, I don't remember exactly what I did there. The problem was that I had to bring the LensInside components 1 mm down. Most of my model was correctly referencing, so the following components nicely moved downwards (I love Fusion 360 for this - especially if you used to work with SketchUp). But my PCB moved down and collided with my pushbutton. If I remember well, I moved the pushbutton down, so that it nicely touched the PCB again. But I remember that I then had some issues with the joint (I guess), that moved everything back upwards, and so I started playing with the move command. I know.... feels more like an uncontrolled panicking solution, and probably not clever. Missing strategy....again.
