Clipping plane allows you to cut through the stress bulbs at any location and by any angle. You can access this function from Tools→Clipping Plane menu or from the corresponding button on the main toolbar.


Once this feature is activated, a green plane will be shown at the ground surface. At the center of this plane 3 arrows and 3 angles are show. Use the blue arrow and angles to move the plane up/down and to change the angle of the plane. The plane cuts through the stress bulb(s) and shows only the part of the bulb(s) located below the clipping plane.
