sw 2017 disabled shady sketch contours

[pippo_tina]

Good morning to all,
know how to disable the new option related to sketch techniques: "shaded contours"
the problem is that if I design a closed contour on a sketch, if there are other lines or entities within it, the area selection does not work well.

thanks for the friendly collaboration
Good day
