The purpose of this dialog is to specify the vertical profile of the canopy. The points are listed in the grid on the left, and drawn in the diagram on the right.

To add a point, put the mouse on the diagram at the desired location and right click. The new point will be inserted between the two existing points whose line segment is closest to the new point.

To remove a point, put the mouse over the point to be removed, and right click.

To move a point, click and drag.

Coordinates are X (parallel to the ground, and cross row, if you have rows) and Z (vertical).

X = 0 is taken to be the center stem of the plant. If all of the X coordinates are > 0, then the program will assume left-right symmetry when drawing the top view of the canopy. If some of the X coordinates are < 0, however, then no symmetry is assumed, and the top view will reflect the maximum left (X<0) and right (X>0) dimensions of your vertical profile.
