                                          for comparison with another object.

cell_height                               MN      ndt_length

                                          The length of a cell in the vertical dimension
                                          within a pattern fill. 

cell_orientation_angle                    MN      ndt_plane_angle

                                          The angle by which a cell is rotated when displayed
                                          in a pattern fill. The angle is measured
                                          counter-clockwise from the horizontal. 

cell_width                                MN      ndt_length

                                          The length of a cell in the horizontal dimension.

horizontal_offset                         N       ndt_length

                                          The distance in the horizontal direction separating
                                          the origin of the display coordinate system and
                                          the origin of one cell in the pattern. This distance
                                          could reference the nearest cell, but any cell
                                          is adequate. 

horizontal_spacing                        MN      ndt_length

                                          The distance separating cell origins along a row
                                          of cells. 

identifier                                MU      ndt_name

                                          The label used to identify an area cell. 

vertical_offset                           N       ndt_length

                                          The distance by which a pattern of cells is displaced
                                          in the vertical direction from the origin of the
                                          display coordinate system. 

vertical_spacing                          MN      ndt_length

                                          The distance by which a cell origin is displaced
                                          from adjacent cell origins in a column of cells.

cell                                      MU      cell

                                          Specifies a cell for participation in the definition
                                          of an area pattern fill. 

pattern_fill                              MV      set[1 .. N] of (area_pattern_fill)

                                          Specifies the area pattern fill in which cells
                                          are included as part of the pattern.
