Delete old curve and create new in Sculpting

I choose Curve as stroke method in sculpting but after i finished it I am unable to delete it, when i choose different stroke method and click on Stroke method as curve again, the old curve reappear.

@kalpit3d Once you finish applying the curve to the mesh, press “a” shortcut on the keyboard to select all (existing) control points and press x. Just delete the old control points and continue with your sculpting work.
