Which standard allows CAD/CAM data to be exchanged between systems in different countries?

Which standard allows CAD/CAM data to be exchanged between systems in different countries?

• A. Standard for the Exchange of Product Model Data (STEP)
• B. IGES
• C. Unified Data Standard
• D. CAD/CAM Interchange

Answer: (A)

Interoperability of CAD/CAM data across borders relies on a neutral, comprehensive standard that can encode geometry along with all the related product information. STEP, the Standard for the Exchange of Product Model Data, was created as an international ISO standard (ISO 10303) specifically for this purpose. It provides a robust, vendor-agnostic data model that covers geometry, topology, tolerances, features, materials, and lifecycle data, so files created in one system can be accurately interpreted by another system anywhere in the world. This international standardization ensures reliable data exchange across countries and software platforms, which is why STEP is the best choice. IGES exists but is older and mainly focuses on geometry with limited semantic data, which can lead to lost or ambiguous information during transfer. The other options aren’t established international standards for cross-border CAD/CAM data exchange, so they don’t provide the same level of interoperability as STEP.
