BlockTable bt = (BlockTable)tr.GetObject(db.BlockTableId, OpenMode.ForRead);
                     BlockTableRecord btr = (BlockTableRecord)tr.GetObject(bt[BlockTableRecord.ModelSpace], OpenMode.ForWrite);
                     Entity entity = tr.GetObject(entityID, OpenMode.ForWrite) as Entity;
                     //MgGeometry geometry = EntityToGeometryConverter.EntityToGeometry(entity);
                     Entity entity2 = tr.GetObject(entityID2, OpenMode.ForWrite) as Entity;
                     DBObjectCollection curveSegments = new DBObjectCollection();
                     curveSegments.Add(entity);
                     DBObjectCollection regions = Region.CreateFromCurves(curveSegments);
                     Region region = regions[0] as Region;
