Namespace: Autodesk.Civil.DatabaseServices
Assembly: AeccDbMgd (in AeccDbMgd.dll) Version: 13.8.0.280

Syntax

C#

public ObjectId SetLabelRotation(
	ObjectId pointId,
	double rotation
)

VB

Public Function SetLabelRotation ( 
	pointId As ObjectId,
	rotation As Double
) As ObjectId

C++

public:
ObjectId SetLabelRotation(
	ObjectId pointId, 
	double rotation
)

Parameters

pointId  ObjectId

The ObjectId of the point you want to set the LabelRotation property for.

rotation  Double

The new LabelRotation value.

Return Value

ObjectId
If the method succeeds, it returns the same ObjectId pointId passed in. If the method fails, it returns ObjectId.Null.

Example

 2// 
 3CogoPointCollection cogoPoints = _civildoc.CogoPoints;
 4ObjectId pointId = cogoPoints.Add(new Point3d(100, 100, 50), false);
 5double rotationAngle = 0.785398163; // 45 degres in rads
 6
 7// set value for single point
 8if (cogoPoints.SetLabelRotation(pointId, rotationAngle) == ObjectId.Null)
 9    write("SetLabelRotation failed.\n");
10
11Point3dCollection points = new Point3dCollection();
12points.Add(new Point3d(50, 50, 25));
13points.Add(new Point3d(200, 200, 15));
14ObjectIdCollection pointIds = cogoPoints.Add(points, false);
15List<ObjectId> pointIdList = GetListFromCollection(pointIds);
16
17// set multiple points to a single value
18ObjectIdCollection success = cogoPoints.SetLabelRotation(pointIdList, rotationAngle);

22List<double> angles = new List<double>();
23for (int i = 0; i < pointIdList.Count; i++)
24    angles.Add(6.28318531 / pointIdList.Count * i);
25
26// set multiple points to multiple values
27success = cogoPoints.SetLabelRotation(pointIdList, angles);
28write(String.Format("SetLabelRotation success for {0} of {1} points\n",
