Control points Control Points

The control points of the terrain division let you modify the contour of the subdivision. They are the same as those of the curved used for this operation. In addition, it has a Move control arrow, to move the whole subdivision position.

These control points are integrated into the terrain and are visible when activating the terrain control points.

They can be disabled from the Input data tab, (in the Properties area of the Edit panel or Properties Explorer dialog), after selecting the subdivision under the Divisions list.
