In what order are drawings in the Ship Drawing Index (SDI) listed?

The Ship Drawing Index (SDI) organizes drawings in a numerical order, which is based on the drawing number assigned to each document. This numbering system helps in easily locating specific drawings, as each number corresponds to a particular technical or design document related to the ship. Numerical indexing allows for efficient referencing and retrieval, especially in large projects where numerous drawings exist.

The alternative options—alphabetical, narrative, and chronological—would introduce complexity and inefficiency in locating specific drawings. Alphabetical organization relies on names, which do not provide a direct way to find technical drawings tied to complex systems. A narrative approach lacks the precision required for technical documentation, while chronological ordering by creation date could be misleading, as it doesn't reflect the functional categories or systems to which the drawings pertain. Therefore, the most effective method for indexing is the numerical system found in the SDI.
