This tool creates an arc of parabola by focus, vertex and endpoints.

Press the Arc of parabola button.
Click in the 3D view to define the focus point (labelled 1 in the picture above).
Click in the 3D view to define the tip of the arc of hyperbola (labelled 2 in the picture above).
Click in the 3D view to define the first end point (labelled 3 in the picture above).
Click a fourth time in the 3D view to define the other end point (labelled 4 in the picture above).

General: Create sketch, Edit sketch, Map sketch to face, Reorient sketch, Validate sketch, Merge sketches, Mirror sketch, Leave sketch, View sketch, View section, Toggle grid, Toggle snap, Configure rendering order, Stop operation
