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
1. The 43 in the aa position denotes the Coral Reef Mission Project.
2. The first digit after the - denotes a major, complete assembly (see Table of Contents).
3. The second and third digits denote a major subassembly.
4. The fourth and fifth digits denotes items constituent to the subassemblies.
5. The first and second digits after the decimal (generally) from a parts list for a lowest level assembly.
6. 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 special case of Verification Reports, the drawing size indicates the number of individual reports contributing to the total. The revision letter will be either a P to indicate the item is partially verified or a C to indicate the item is complete.

3. Drawings which show *** ? *** under the Description column will be purchased parts that have not yet been selected.

4. Archives of drawings and documents are kept in the CRM file_cabinet directory. The file name is of the form bccdd_eeffSk_rn.type and is write-protected from all access but that of the configuration manager.
   1. The first digits (bccdd_eeff) are the same as those in the Configuration Database. The 85- is missing, and the dots are replaced with an underscore.
   2. In the case of a multi-sheet drawing, a capital S followed by a page number k preceeding the .rn suffix.
   3. The revision number n of the drawing is an upper-case alphanumeric -- e.g. 01 or C. Typically, all revisions, past as well as current, are kept on file.
   To make the file system more accessible, a directory structure based on the first few digits' meaning is used. For example 43-12345_06_rK.dwg would be found in a directory ../file_cabinet/1/23/45/12345_06 along with all prior revisions.
