    Default How to draw a circle exactly center on a plane?

    I draw a plane on spline: 1.JPG

    But I can't draw a circle exactly center on a plane: 2.JPG

    It slightly away from the center.

    You need to constrain the circle to the curve, but first you need a point.

    There are many ways to do this, but here is one way:
    1. edit the circle sketch
    2. draw a point where the sketch plane intersects the curve
    - a. INSERT (top menu) + OPERATIONS + INTERSECT 3D ELEMENTS
    - b. select the spline curve
    3. constrain the circle centerpoint and the intersection point as COINCIDENT
    4. add dimension for the size of the circle
    5. EXIT the sketch

    When I'm modeling a tube or wire and I'm using a spline as the centerline; I build the sketch plane at one of the endpoints of the spline. Then I use that endpoint to center the circle.
