DEC drawing codes, embedded in the drawing numbers of DEC engineering drawings, allow one to discern what kind of information is conveyed in that particular drawing. A DEC drawing number will be of the form AA-bbbb-x-yy, where 'AA' is the drawing code, 'bbbb' is the device which the drawing is of, 'x' (a digit) is the 'manufacturing series', and 'yy' is the page number within the set.
The list of drawing codes, as of circa 1964, was:
| Code | Meaning |
|---|---|
| AD | Assembly Drawing |
| AR | Arrangement Drawing |
| BD | Functional Block Diagram |
| CD | Cable Diagram |
| CP | Component List |
| CS | Circuit Schematic |
| FD | Flow Diagram |
| IC | Interface Cabling Diagram |
| LO | Layout Drawing |
| MU | Module Utilization Drawing |
| PL | Parts List |
| RS | Replacement Schematic |
| SD | Specification Drawing |
| TD | Timing Diagram |
| UA | Unit Assembly |
| WD | Wiring Diagram |
| WL | Wiring List |
