CogoPointCollection.SetElevation(IEnumerable<ObjectId>, IEnumerable<Double>) Method

Sets the elevation for multiple CogoPoints with different elevation values.

Namespace: Autodesk.Civil.DatabaseServices
Assembly: AeccDbMgd (in AeccDbMgd.dll) Version: 13.8.0.1516

Syntax

C#

public ObjectIdCollection SetElevation(
	IEnumerable<ObjectId> pointIds,
	IEnumerable<double> elevations
)

VB

Public Function SetElevation ( 
	pointIds As IEnumerable(Of ObjectId),
	elevations As IEnumerable(Of Double)
) As ObjectIdCollection

C++

public:
ObjectIdCollection^ SetElevation(
	IEnumerable<ObjectId>^ pointIds, 
	IEnumerable<double>^ elevations
)

Parameters

pointIds  IEnumerableObjectId

A sequence of ObjectIds for the points you want to set the elevation for.

elevations  IEnumerableDouble

 

Return Value

ObjectIdCollection
An ObjectIdCollection containing the CogoPoints which have their elevation set successfully.

Remarks

• If you want to set to the state of "Has not beet set" for all the CogoPoints, set the elevation to Double.NaN.
• If there are fewer elevations than points, only the first n points in the list will have their elevation set, where n is the number of elevations specified.

Example

C#

 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.SetElevation(pointId, 125) == ObjectId.Null)
 8    write("SetElevation failed.\n");

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.SetElevation(pointIdList, 125);
