Autodesk Inventor vs CATIA

Autodesk Inventor is Windows software for mechanical design, documentation, simulation, and model-based definition. Its 3D tools combine parametric, direct, freeform, and rules-based modeling, with support for assembly design, sheet metal, and surfaces. Inventor can open designs from other CAD systems without translation. Parts can be exported to formats including DWG, IGES, JT, OBJ, STEP, and STL; assembly exports also include RVT, while drawings support DWG, IDW, DWF/DWFx, and DXF. Design connections include Revit family data, Vault, Factory Design Utilities, and Inventor Nastran. Automation options include iLogic, the API, and Autodesk Platform Services. Inventor is paid, with a 30-day trial and no permanent free tier. Displayed monthly, annual, and three-year prices are placeholders, not figures. A subscription permits installation on up to three devices, but only the named user may sign in and use it on one computer at a time.

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.
