Example
 1// _civildoc is the active CivilDocument instance.
 2// 
 3CogoPointCollection cogoPoints = _civildoc.CogoPoints;
 4ObjectId pointId = cogoPoints.Add(new Point3d(100, 100, 50), false);
 5
 6// set value for single point
 7if (cogoPoints.SetElevationByOffset(pointId, -10) == ObjectId.Null)
 8    write("SetElevationByOffset failed.\n");
 9
10Point3dCollection points = new Point3dCollection();
11points.Add(new Point3d(50, 50, 25));
12points.Add(new Point3d(200, 200, 15));
13ObjectIdCollection pointIds = cogoPoints.Add(points, false);
14List<ObjectId> pointIdList = GetListFromCollection(pointIds);
15
16// set multiple points to a single value
17ObjectIdCollection success = cogoPoints.SetElevationByOffset(pointIdList, -15);
18write(String.Format("SetElevationByOffset success for {0} of {1} points\n",
19  success.Count, pointIdList.Count));
20
21List<double> offsets = new List<double>();
22for (int i = 0; i < pointIdList.Count; i++)
23    offsets.Add(i * -10);
24
25// set multiple points to multiple values
26success = cogoPoints.SetElevationByOffset(pointIdList, offsets);
27write(String.Format("SetElevationByOffset success for {0} of {1} points\n",
28  success.Count, pointIdList.Count));
