In the mode Spline form You can select one or multiple poles of the grid. Poles may be positioned arbitrarily or belong to a single row.
Poles of the grid are displayed in the graphic area as circles. If the pole is not selected, the circle is blank. If the pole is selected, the circle is color–filled.
If you select a series of poles, the segments of this series are highlighted, and all its poles are displayed as color–filled.
After you select a pole (or a series of poles), the Placement element
appears.
