you clicked, and aligned so that its normal is on the line itself, facing towards the camera.
■ Align To Surface
- enables you to pick a surface, and place the section plane ‘on’ that surface, with its
normal aligned to the normal of the triangle picked.

Slider Behavior
The slider behavior depends on the selected mode of section alignment. By default, the range of slider represents
the entire extents of the model in the selected direction. For example, for section planes aligned to top, moving
the slider moves the plane from the very top to the very bottom of the model; for section planes aligned to
bottom, moving the slider moves the plane from the very bottom to the very top of the mode, and so on.
It is possible to restrict the range of the slider movement, and set a finer resolution for sectioning large models.
The Set Range
button enables you to limit the range of the section planes to the bounding box limits of
the currently selected items. Clicking this button with nothing selected resets the range back to default.
You can also control the Step Size of the slider; it dictates the incremental value by which the slider moves when
you single-click rather than drag on it.
If the Step Size in not enabled, the slider will move at percentage intervals when you single-click on it.
