NICER Database Decoder

What do all these funny numbers mean?
- The drawing number system for this project is described in the following for a typical drawing: aa-bbccdd.eeff
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.
- The 38 in the aa position denotes the NICER 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.
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.
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.
Drawings which show *** ? *** under the Description column will be purchased parts that have not yet been selected.
The parent drawings as well as PDF versions are filed in the NICER 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.
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.
