Control points are the “known” or “fixed” locations that other survey points are based from. The collection of control points in a network is held in the AeccSurveyNetwork.ControlPoints property. New control points can be added to the network through the collection’s Create method. Create adds a new point with the specified features to the AeccSurveyControlPoints collection and returns a reference to the newly created AeccSurveyControlPoint object.
