LLAMAS Database Decoder

What do all these funny numbers mean?

1. The drawing number system for this project is described in the following for a typical drawing: aa-bbccdd.eeff
• The 60 in the aa position denotes the TESS Project.
• The first digit after the - denotes a major, complete assembly (see Table of Contents).
• The second and third digits denote a major subassembly.
• The fourth and fifth digits denotes items constituent to the subassemblies.
• The first and second digits after the decimal (generally) from a parts list for a lowest level assembly.
• The third and fourth digits after the decimal are available if further breakdown is necessary.

2. Drawing size is indicated by prefixing the drawing size letter to the number. A T indicates a text document. A number prefix is also used for the number of sheets, ( e.g. 2B ). Controlled purchased parts are indicated by a > in this column.

   Revisions are shown by a letter in the Rev column. Initial releases are designated as A. Pre-released revisions are indicated by a number starting with 01. In the case of documents owned by other organizations, the revision letter is followed by an m, indicating that this is a "mirrored" copy. 

3. The parent drawings as well as PDF versions are filed in the LLAMAS data directory. The file name is of the form bccdd_eeffSk.rn and is write-protected from all access but that of the configuration manager.
   • The first digits (bccdd_eeff) are the same as those in the Configuration Database. The 37- is missing, and the dot is replaced with an underscore.
   • In the case of a multi-sheet drawing, a capital S followed by a page number k preceeding the .rn suffix.
   • The suffix contains the revision number n of the drawing as an upper-case alphanumeric -- e.g. 01 or C. Typically, all revisions, past as well as current, are kept on file.

4. Sometimes numbers are assigned for things we know we'll need, but haven't gotten there yet. If a drawing does exist, clicking on the DWG # link will bring up a PDF version. Clicking on the REV link will bring you to the directory containing the current and past versions, in the original format as well as PDF.
