CogoPointCollectionSetElevationByOffset(IEnumerableObjectId, IEnumerableDouble) Method

Sets 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 SetElevationByOffset(
	IEnumerable<ObjectId> pointIds,
	IEnumerable<double> offsets
)

Public Function SetElevationByOffset ( 
	pointIds As IEnumerable(Of ObjectId),
	offsets As IEnumerable(Of Double)
) As ObjectIdCollection

public:
ObjectIdCollection^ SetElevationByOffset(
	IEnumerable<ObjectId>^ pointIds, 
	IEnumerable<double>^ offsets
)

Parameters

pointIds IEnumerableObjectId: A sequence of ObjectIds of the points you want to set the elevation for.
offsets IEnumerableDouble: A sequence of offset values to apply to each corresponding point's current elevation.

Return Value

ObjectIdCollection
An ObjectIdCollection containing the CogoPoints for which the elevation has been set successfully.

Remarks

If there are fewer offsets than points, only the first n points in the list will have their elevation set, where n is the number of offsets specified.
