this.editing$.subscribe((editUpdate: HippodromeEditUpdate) => {

      if (editUpdate.editAction === EditActions.DRAG_POINT || editUpdate.editAction === EditActions.ADD_POINT) {
        console.log('width', this.editing$.getCurrentWidth());
        console.log('positions', this.editing$.getCurrentPoints());

        // or
        console.log('width', editUpdate.width);
        console.log('positions', editUpdate.points); // cartesian3
      }
    });
  }

this.editing$.subscribe((editUpdate: PolylineEditUpdate) => {

      if (editUpdate.editAction === EditActions.ADD_POINT) {
        console.log(editUpdate.points); // point = position with id
        console.log(editUpdate.positions); // or just position
        console.log(editUpdate.updatedPosition); // added position
      }
    });
  }
