CATIA vs StrictDoc

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.

StrictDoc is open-source software for technical documentation and requirements management. It stores requirements and documentation as plain-text files that teams can version with Git, using SDoc or a Markdown dialect with traceability features. Requirements can link to source code, tests, and test reports, with navigation through a traceability graph. StrictDoc reports source-code coverage by requirement and generates diffs and changelogs between document-tree versions. Users can edit and review documents in a browser, IDE, or command-line workflow. Custom document grammars define project-specific fields and mandatory values. Exports include HTML and reStructuredText, with the latter feeding a Sphinx pipeline; PDF export is experimental. ReqIF import and export are experimental, and Excel XLS/XLSX and JSON are listed formats. A Python API supports extensions and engineering integrations. StrictDoc requires Python 3.10 or newer, runs a local web server, and offers pip and Docker installation paths. It is licensed under Apache License 2.0 and targets agile teams, safety- and security-critical projects, documentation teams, and university or research projects.
