Why sketch plan doesn't move along when moving an object?

[Anonymous]

I created a sketch on XY plane and made a box out of it.  When I move the box, why the sketch stay on its original location and not moving along with the object?   Is this what it should be?

Use Joints, not Move.

@TheCADWhisperer I'm very new to 3D modeling.  I'll create a lot of other parts on other locations on a plan (xy, xz, yz) and will move them around to the right position.  I look quickly on "joints" as you suggested and got an impression that it is used for moving part.  My pieces is static, they stay where they are.  I'll give "joints" a try.

From my picture, do you know what is that light blue box? Why it is there? It's very strange seeing it is still there while I've already moved my object.

1. this only happens when a component is moved, in which both the sketch and the body are located
2. joints can also be fixed connections of components that define their position to each other.
3. this is the sketch profile of sketch 7. this also appears when the sketch group is disabled but the sketch is clicked.

Fusion 360 works on a time based structure, you have to align your thinking with this to work with it. 

In your example the planes are generated when you start a new component, you then draw a sketch onto one of these planes, then you extrude a box, then you move the box. Fusion 360 remembers these steps in that order. The sketch doesn't move because you moved the box not the sketch.

If you roll back you timeline to before the extrude and move the sketch, then the sketch has moved and so when you roll the time forward again both the sketch and extrude will move.  

You want to avoid having to use the "move" and "capture position" tools as much as possible, models are more robust if you build them where you want them to be and use joints to hold them in place. 

Hope that helps.
