Use this procedure to generate a boundary for a hatch whose original boundary has been deleted or moved during the course of other drawing operations. The boundary generated by this procedure is a polyline. Polylines are also created for any islands within the selected hatch. These polylines remain selected after you generate the boundary, so you can directly manipulate them into the desired configuration. You can then apply the hatch to the new boundary configuration using the Set Boundary option.
All grips are displayed for any polylines created.
