    1.create datum tangent to the surface.
    2.draw hole on that datum using sketch.
    3.By extrude and subtract it to make hole.
    4.Instance geometry...> on path option ....>to select the curved edge ...>then give number of copy and angle.
    5.Then extrude sktches induvidually.

    Im looking for it to be on the curved parts. the flat area that you did was easy but im stuck on the curved areas.

    I'm not too sure I understand what the question is. In the attached model the upper set of hole is simply a hole placed on the midpoint of the sketch line, then arrayed about the center axis of the part.

    The second set of holes uses the sketch to drive a law curve helix (2 turns) that matches the conical shape in that area. The helix is then used to create an equally spaced point set , starting at 30% of the helix and ending at 70%. When you select this point set in the model tree, then select the hole command, a hole is created normal to the surface at each point.

    So, you can create a pattern of holes on a curved surface by arraying a hole or hole set, or you can map points on a surface by sketching, dividing a curve, or other means and use that point set to locate the holes.
