SD-02 shop drawings have size constraints; what are they?

• A. Not less than 8 1/2 by 11 inches and not more than 30 by 42 inches, except for full size patterns or templates
• B. Always letter size
• C. Any size is acceptable as long as clear
• D. A0 size only

Answer: (A)

Size control for SD-02 shop drawings is set to keep drawings readable, easy to review, and simple to file. The standard requires a sheet size not less than 8 1/2 by 11 inches and not more than 30 by 42 inches, with an exception for full-size patterns or templates when such an approach is necessary for accuracy or fabrication. This range balances practical printing and handling with enough space to show clear details and scales. Larger formats would be unwieldy and harder to manage, while smaller formats risk illegibility. The exception for full-size patterns ensures that critical fit information isn’t distorted by scaling.
