Which element may be found on a sheet metal pattern drawing to convey additional information?

• A. Edge length
• B. Bend angle
• C. Pattern note
• D. Hole diameter

Answer: (C)

Pattern notes are the place on a sheet metal pattern drawing to convey information that isn’t tied to a specific dimension or feature. They carry instructions and qualifiers that affect how the part is made or treated—things like material type and thickness, finish, coating, deburring, bend sequence, tolerances, or special handling. The other options specify concrete geometric details: edge length describes a size, bend angle defines the formed shape, and hole diameter fixes a feature’s dimension. Those elements communicate what the part must look like and how to fabricate it, while the pattern note communicates the extra instructions that guide the process as a whole. That combination makes the pattern note the appropriate way to convey additional information.
