CogoPointCollectionSetLabelRotation(IEnumerableObjectId, IEnumerableDouble) Method

Sets the LabelRotation property for multiple CogoPoints with different values.

Namespace: Autodesk.Civil.DatabaseServices
Assembly: AeccDbMgd (in AeccDbMgd.dll) Version: 13.8.0.292
Syntax
public ObjectIdCollection SetLabelRotation(
	IEnumerable<ObjectId> pointIds,
	IEnumerable<double> values
)

Parameters

pointIds  IEnumerableObjectId
A sequence of ObjectIds of the points you want to set the LabelRotation property for.
values  IEnumerableDouble
A sequence of doubles to set the corresponding point's LabelRotation property to.

Return Value

ObjectIdCollection
An ObjectIdCollection containing the CogoPoints for which the LabelRotation property has been set successfully.
Remarks
If there are fewer doubles than points, only the first n points in the list will have their LabelRotation property set, where n is the number of items in the values list.
Example
 1// _civildoc is the active CivilDocument instance.
 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);
19write(String.Format("SetLabelRotation success for {0} of {1} points\n",
20  success.Count, pointIdList.Count));
21
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",
29 success.Count, pointIdList.Count));
