Data File Maintenance
The Data File Maintenance allows access to the files for the current data set which include: Assemblies, Databook, Design Specifications, Subtotals, Formulas, Hanger Spacing, Levels, Phases, Sections, Sizes, Specials, and Subtotals.
Generally, each data set in Data File Maintenance will be split into a Tree and a List, as seen in Figure 1. The left portion of the display contains the tree, and the header panel for the tree. The right portion of the display contains the list. Above the list are bands and headers. A band is a general grouping that contains several headers. The band is a darker shade of gray than the header.
Figure 1
For more information on bands and headers, see Basic Data File Maintenance Functions.
