AbstractThe National Standard of Canada CAN3-B78.3-M77--Building Drawings, was one of the first metric standards related to the building industry. It provided designers and builders with an important tool to assist in the change to SI. The codifying language of the standard, and its size, however, did not allow for explicit explanations of each rule established in it. In this commentary, the authors' intent is to describe the rationale behind the standard. Various basic rules on metric usage are presented in Part 1 of the commentary. Consequent rules for the preparation of working drawings are presented in Part 2. Part 3 consists of a selection of the set of drawings included in the standard which serve to illustrate the rules and practices outlined in Parts 1 and 2. Part 4 covers additional information usually included in a set of architectural working drawings but not included in the standard.
