CATPart

CATPart is a file format commonly associated with Dassault Systèmes' CATIA software. CATIA, which stands for Computer Aided Three-Dimensional Interactive Application, is a widely used suite of computer-aided design (CAD), computer-aided engineering (CAE), and computer-aided manufacturing (CAM) software. The CATPart file extension specifically denotes a part file, representing a single component or assembly within a larger design.

These files contain detailed three-dimensional geometric data, including features, sketches, parameters, and manufacturing information necessary to define and manipulate a solid model. CATPart files are integral to the product lifecycle management process, enabling engineers and designers to create, analyze, and manufacture complex parts. The format is proprietary to Dassault Systèmes, meaning that while other software might offer import or export capabilities, full compatibility and editing are typically best achieved within CATIA itself.

The structure of a CATPart file allows for parametric modeling, where design changes can be made by modifying underlying parameters, which then automatically update the geometry. This makes it a powerful tool for iterative design and for managing complex assemblies where individual components need to be modified. CATPart files are fundamental building blocks for creating complete product designs within the CATIA ecosystem.
