Which item describes a physical drawing used to communicate specifications to fabricators?

• A. Hard copy in CAD
• B. Digital drawing
• C. Toolpaths in CAM
• D. Post-processing

Answer: (A)

The point being tested is how information is communicated to fabricators: what actually exists as a tangible reference on the shop floor versus digital data or process instructions. A physical drawing released as a hard copy from CAD is the standard way to convey exact specifications in a form that everyone can use without needing software. It captures dimensions, tolerances, material notes, finishes, and any special instructions in a single, portable document that can be marked up and referenced at the machine. A digital drawing, while essential for design work, is just a file kept on a computer or network and isn’t automatically a physical reference for those on the shop floor. Toolpaths in CAM are the machine’s instructions for cutting or shaping, not drawings used to communicate geometry or specifications. Post-processing refers to finishing steps after fabrication, not to how specifications are conveyed.
