CATIA vs Siemens NX

CATIA is a parametric modeling and engineering product with tools for assembly design, sheet-metal work, and surface modeling. It supports cloud collaboration. Platform availability depends on the CATIA product: browser applications run on the 3DEXPERIENCE platform, while CATIA V5 sheet-metal software is available for Windows. File format support also varies by product. STEP import and export are listed, while DXF, STL, VRML, and IGES are supported by other CATIA V5 products. CATIA is paid, with pricing on request. Buyers should match the intended modeling work, collaboration needs, platform, and file exchange requirements to the specific CATIA product. Its web and Windows listings do not mean that every CATIA capability is offered on both platforms.

Siemens NX is a product development suite spanning design, engineering, and manufacturing. It uses hybrid modeling and includes assembly design, sheet-metal tools, and surface modeling. Windows desktop use is supported, while NX X Design provides browser access as a cloud SaaS service with built-in data management. NX X Design has Essentials, Standard, Advanced, and Premium tiers, built on a common core with progressively added functionality. The tiers can share data without translation with other Siemens Xcelerator software. NX supports IGES, STEP AP203, STEP AP214, DXF/DWG, STL, and 3MF; NX X data exchange also lists JT, Solid Edge, and SolidWorks open. Design Copilot NX answers questions using documentation for the user's NX version and can link to documentation or launch mentioned commands. Other listed tools include virtual and augmented reality design, model-based inspection characteristics, sketch checking with automatic correction, and routed-systems design with rule checking. NX is paid, with pricing on request and a 30-day free trial; no free plan is listed.
