Add/Edit Control Points

You may enter individual control points or a polyline of control points to grid along with your data. Once you have entered a control point or points you may change the mode to Make Changes.

In Make Changes mode you can change the z value of an individual point or all the points in a polyline. You can also manually edit the X and Y coordinates or use sliders to reposition the control points.
