Sheet file names consist of the building code, followed by a discipline designator, either a single character with underscore (Level 1) or two character (Level 2); followed by the sheet type designator, followed by the sheet sequence number; usually a two-character field starting at 01 and continuing through 99. Use of a three-character user definable field is optional.

Within the two-character discipline designator, the first character is the discipline character and the second is the modifier. The modifier is used to subdivide the information for a specific use or purpose, such as project complexity, or need for specialization in intricate fields. For example 00001_AD101 would be the first architectural demolition plan in the set.
