BoundarySegment Class

An object that represents a segment of an area boundary.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 16.0.0.0 (16.0.0.0)

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

Copy C# 
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)
         {

            // Get curve start point
            message += "\nCurve start point: (" + boundarySegment.GetCurve().GetEndPoint(0).X + ","
                           + boundarySegment.GetCurve().GetEndPoint(0).Y + "," +
                          boundarySegment.GetCurve().GetEndPoint(0).Z + ")";
            // Get curve end point
            message += ";\nCurve end point: (" + boundarySegment.GetCurve().GetEndPoint(1).X + ","
                 + boundarySegment.GetCurve().GetEndPoint(1).Y + "," +
                 boundarySegment.GetCurve().GetEndPoint(1).Z + ")";
            // Get document path name
            message += ";\nDocument path name: " + room.Document.PathName;
            // Get boundary segment element name

            }
         }
      }
      TaskDialog.Show("Revit",message);
   }
}
