I have tried to fully define my sketch but I cant make it work with the arc. Do you have any suggestions?
Ad coincident constraint on the end point of the arc and the outer diameter (you can see that it is blue).
Why are you doing this sketch as a 3DSketch?
Isn't that geometry actually 2D?
What do you observe if you attempt to drag the arc?
Attach your file here.
Maybe this will help?

Although I agree with J. Mather in that, if you don't need a 3D sketch it is best not to use one.
...also,.. (if you prefer to use a 3DSketch)... check that the Arc is on the Plane..(image)
Thank you !!
