CATIA vs OSRMT

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.

OSRMT is a free, configurable open-source tool for defining and managing software requirements. Its workflow spans features, requirements such as use cases, design, implementation, and test cases, while tracking how requirements connect and progress. Work can be organized by phase, and teams can configure the tool and manage multiple projects at once. The project describes both a single-user desktop application and a multiuser web application with a centralized server and desktop or web client. The README lists Windows, Linux (CentOS), and macOS as tested systems. Desktop setup requires one of those operating systems, an archive utility, and JRE 1.8 or later. The web version deploys on JBoss and is accessible locally on port 8080. Oracle, MySQL, MS SQL, and PostgreSQL are listed as external database options; no additional database setup is required for initial use. The project uses the GNU GPL-2.0 license. Users can look to issue reports, a request process, an FAQ, online source and documentation, and a community support email address.
