Which tool is used with 3D CAD for inputting measurements?

• A. CADIn
• B. AutoCAD
• C. FaroArm
• D. anyKode Marilou

Answer: (C)

When you need to bring real-world measurements into a 3D CAD model, you rely on a measurement input device rather than just software. A FaroArm is a handheld articulated measuring arm with a touch probe that captures exact coordinates of features on a physical part. Those measured points are then loaded into the CAD system, enabling accurate digitization, reverse engineering, or verification against the design.

AutoCAD, while a powerful CAD program, is not a dedicated measurement input tool for capturing real-world geometry; you’d typically enter dimensions manually or use separate measurement devices to generate data for AutoCAD. The other names listed don’t correspond to standard measurement-input hardware used with 3D CAD.
