Since:  2014

Syntax

C#
public void ChangePointElevation(
	XYZ point,
	double elevationValue
)
Visual Basic
Public Sub ChangePointElevation ( _
	point As XYZ, _
	elevationValue As Double _
)
Visual C++
public:
void ChangePointElevation(

Parameters

point
Type: Autodesk.Revit.DB..::..XYZ
The point to be modified.

Type: System..::..Double
The new elevation value.

Remarks

If the point doesn't exist in the current TopographySurface, an exception will be thrown. This applies to a TopographySurface element (not a SiteSubRegion or a topography surface associated with a BuildingPad), which should be in an active TopographyEditScope.
