Sets the LabelRotation property for multiple CogoPoints with different values.

Namespace: Autodesk.Civil.DatabaseServices
Assembly: AeccDbMgd (in AeccDbMgd.dll) Version: 13.4.2516.0

Syntax

C#
public ObjectIdCollection SetLabelRotation(
	IEnumerable<ObjectId> pointIds,
	IEnumerable<double> values
)
Visual Basic
Public Function SetLabelRotation ( _
	pointIds As IEnumerable(Of ObjectId), _
	values As IEnumerable(Of Double) _
) As ObjectIdCollection
Visual C++
public:
ObjectIdCollection^ SetLabelRotation(
	IEnumerable<ObjectId>^ pointIds, 
	IEnumerable<double>^ values
)

Parameters

pointIds
Type: System.Collections.Generic..::..IEnumerable<(Of <(<'ObjectId>)>)>
A sequence of ObjectIds of the points you want to set the LabelRotation property for.
values
Type: System.Collections.Generic..::..IEnumerable<(Of <(<'Double>)>)>
A sequence of doubles to set the corresponding point's LabelRotation property to.

Return Value

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.
