In their own words
CATIA
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.
