BoundarySegment Class
An object that represents a segment of an area boundary.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 23.0.0.0 (23.1.0.0)

Syntax

C#
public class BoundarySegment : IDisposable
Visual Basic
Public Class BoundarySegment _
	Implements IDisposable
Visual C++
public ref class BoundarySegment : IDisposable

Remarks

These objects define the exterior boundary of an area. The geometry of the segment can be retrieved along with the id of the element that is responsible for producing that boundary.

Examples

CopyC#
public void GetInfo_BoundarySegment(Room room)
{
   IList<IList<Autodesk.Revit.DB.BoundarySegment>> segments = room.GetBoundarySegments(new SpatialElementBoundaryOptions());

   if (null != segments)  //the room may not be bound
   {
      string message = "BoundarySegment";
      foreach (IList<Autodesk.Revit.DB.BoundarySegment> segmentList in segments)

         foreach (Autodesk.Revit.DB.BoundarySegment boundarySegment in segmentList)
