BoundarySegment Class

An object that represents a segment of an area boundary.

Inheritance Hierarchy

System.Object
Autodesk.Revit.DB.BoundarySegment

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.3.0.0 (25.3.0.0)

Syntax

C#

public class BoundarySegment : IDisposable

The BoundarySegment type exposes the following members.

Properties

	Name	Description
	ElementId	Retrieve the id of the element that produces this boundary segment. If the segment is created from an element in a link, this is the id of the RevitLinkInstance.
	IsValidObject	Specifies whether the .NET object represents a valid Revit entity.
	LinkElementId	Retrieve the element id of the element in a link instance that forms this boundary.

Methods

	Name	Description
	Dispose	Releases all resources used by the BoundarySegment
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
	GetCurve	Get a copy of the curve that is formed along this boundary.
	GetHashCode	Serves as the default hash function. (Inherited from Object)
	GetType	Gets the Type of the current instance. (Inherited from Object)
	ToString	Returns a string that represents the current object. (Inherited from Object)

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.

Example

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
            if (boundarySegment.ElementId != ElementId.InvalidElementId)
            {
               message += ";\nElement name: " + room.Document.GetElement(boundarySegment.ElementId).Name;
            }
         }
      }
      TaskDialog.Show("Revit",message);
   }
}
