Sets the LabelRotation property for a single CogoPoint.

Namespace: Autodesk.Civil.DatabaseServices
Assembly: AeccDbMgd (in AeccDbMgd.dll) Version: 10.3.488.0

Syntax

C#
public ObjectId SetLabelRotation(
	ObjectId pointId,
	double rotation
)
Visual Basic
Public Function SetLabelRotation ( _
	pointId As ObjectId, _
	rotation As Double _
) As ObjectId
Visual C++
public:
ObjectId SetLabelRotation(
	ObjectId pointId, 
	double rotation
)

Parameters

pointId
Type: ObjectId
The ObjectId of the point you want to set the LabelRotation property for.
rotation
Type: System..::..Double
The new LabelRotation value.

Return Value

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