Revit, wie man position, Länge und Höhe in einer ausgewählten Wand

Habe ich diesen code, und ich weiß nicht, wie ich das anzeigen der position, die Höhe und die Länge von meinem ausgewählten Wand:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using Autodesk.Revit.DB;
using Autodesk.Revit.DB.Architecture;
using Autodesk.Revit.UI;
using Autodesk.Revit.UI.Selection;
using Autodesk.Revit.ApplicationServices;
using Autodesk.Revit.Attributes;
namespace PickSelectionFiltered
{
    [TransactionAttribute(TransactionMode.Manual)]
    [RegenerationAttribute(RegenerationOption.Manual)] 

    public class Class1: IExternalCommand
    {
        public class MySelectionFilter : ISelectionFilter
        {
            Document m_doc = null;

            public bool AllowElement(Element element)
            {
                return element is Wall;
            }
            public bool AllowReference(Reference refer, XYZ point)
            {
                GeometryObject geoObject = 
                m_doc.GetElement(refer)
                     .GetGeometryObjectFromReference(refer);
                return geoObject != null && geoObject is Face;
            }
        }


        public Result Execute(ExternalCommandData commandData, 
          ref string message, ElementSet elements)
        {
            //Get application and document objects
            UIDocument uidoc = commandData.Application.ActiveUIDocument;

            try
            {
                while (true)
                {
                    Reference selRef = 
                      uidoc.Selection.PickObject(ObjectType.Element, 
                        new MySelectionFilter(), "select a room");
                    /*
                     * Add the code to get position, lenght and height
                     * */
                }

            } catch (Autodesk.Revit.Exceptions.OperationCanceledException) { }

            return Result.Succeeded;
        }
    }
}
