Namespace: Autodesk.Revit.DB.Architecture
Assembly: RevitAPI (in RevitAPI.dll) Version: 22.0.0.0 (22.1.0.0)
Since: 2014

Syntax

C# 
public void DeletePoints(
	IList<XYZ> points
)
Visual Basic 
Public Sub DeletePoints ( _
	points As IList(Of XYZ) _
)
Visual C++ 
public:
void DeletePoints(
	IList<XYZ^>^ points
)

Parameters

points
Type: System.Collections.Generic IList XYZ
A collection of points to be deleted.

Remarks

Points will be deleted if they matched in XY. This function ignores input points that do not exist, unless all of the input points do not exist, which will result in an exception. This applies to a TopographySurface element (not a SiteSubRegion or a topography surface associated with a BuildingPad), which shoule be in an active TopographyEditScope.
