A survey network also contains a collection of non-control points, which represent points within a survey network whose location is determined by observation, but are not connected to other survey observations and remain unaffected by a network analysis. These non-control points are represented by objects of type AeccNonControlPoint, and are defined by an easting, northing, and an optional elevation. The collection of all non-control points in a survey network are held in the AeccSurveyNetwork.NonControlPoints property.
' Create a non-control point with an id number of 3006 at ' the location 4950.0, 5000.0, elevation 100.0. Dim oNonControlPt As AeccSurveyNonControlPoint Set oNonControlPt = oSurveyNetwork.NonControlPoints.Create( _ 3006, "NonControlPoint_01", "Description of non-control point", 4950#, 5000#, 100#)
A non-control point may be promoted to a control point if you reference the point as a control point when creating a traverse, or reference the point as a setup to make observations to other points that may affect locations during an analysis.
