CogoPointCollectionSetElevation(IEnumerableObjectId, IEnumerableDouble) Method

Sets the elevation for multiple CogoPoints with different elevation values.

Namespace: Autodesk.Civil.DatabaseServices
Assembly: AeccDbMgd (in AeccDbMgd.dll) Version: 13.8.0.292

Syntax

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

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

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.
