How to set endpoints of a sweep?


Beginners question, I tried to sweep a circular cutout on the outside of a solid. Sketch 4 is the circle.

The endpoints of Sweep1 did not turn out as I expected, I had expected the sweep to run a full 360 .

How can I set the endpoints?

    What did you use for your path?

    I used the outer surface of the large extrusion 1 for path. Just curious what defines start and end of the sweep.
    Tried revolve instead, as suggested, and that gave me a full 360 cutout.

    @ lars_andersson , For sweep,start and end point of sweep curve defines the start and end point.

    You can select one direction option in revolve,

    A brief explanation of why, despite what @Narayan_K says, your sweep stops short of the end of the path, on the side nearest the viewer in your screengrab:

    This is because the swept cut starts before the beginning of the path.

    It starts at the profile sketch, in midair, and travels some distance before it starts cutting into your part.

    I made a public document "Prov 2" there i made  "Revolve 1" and  "Sweep 1" from "Sketch 4"
    "Sweep 1" is made along the intersection edge of "Revolve 1" and "Extrude 1".

    I do not understand why "Sweep 1" ends squarely slightly after the Top plane

    Hope it is this one:

    I think I see something now, the length of the sweep is taken from the sweep target, but the sweep is moved forward by the distance between the sweep source and the sweep target.
