public ObjectIdCollection SetElevationBySurface(
	IEnumerable<ObjectId> pointIds,
	ObjectId surfaceId
)

Parameters

pointIds  IEnumerableObjectId
A list of ObjectIds of the points you want to set the elevation for.

The ObjectId of the Surface object you want to get the elevation from.

Return Value

ObjectIdCollection
An ObjectIdCollection containing the CogoPoints for which the elevation has been set successfully.
Example
Copy
 1// _civildoc is the active CivilDocument instance.
 2CogoPointCollection cogoPoints = _civildoc.CogoPoints;
 3ObjectId pointId = cogoPoints.Add(new Point3d(100, 100, 0), false);

 5// Set elevation for a single point:
 6if (ObjectId.Null == cogoPoints.SetElevationBySurface(pointId, tinSurfaceId))
 7{ write("SetElevationBySurface failed, perhaps the point is outside the surface?\n"); }
 8else
 9{
10    CogoPoint point = pointId.GetObject(OpenMode.ForRead) as CogoPoint;
11    write("Point's new elevation from surface: " + point.Elevation);
12}

14// Create multiple points to set elevation for:
15Point3dCollection pointCollection = new Point3dCollection();
16pointCollection.Add(new Point3d(100, 110, 0));
17pointCollection.Add(new Point3d(110, 100, 0));
18ObjectIdCollection pointIdCollection = cogoPoints.Add(pointCollection, "Example Points", false);
19List<ObjectId> pointIdList = new List<ObjectId>();
20foreach (ObjectId id in pointIdCollection) { pointIdList.Add(id); }
21
22// Set elevation for multiple points: 
23ObjectIdCollection successfullySetPoints = cogoPoints.SetElevationBySurface(pointIdList, tinSurfaceId);
24write(String.Format("Successfully set elevation for {0} of {1} points.\n",
25    pointIdCollection.Count, successfullySetPoints.Count));
