PTC Creo is a suite of design and engineering software applications used to create and analyze 3D models, assemblies, and 2D drawings. It is ideal for product design and engineering teams who need a powerful and flexible solution to create and modify complex 3D designs. The software enables users to build, test, and collaborate on 3D models, as well as to create detailed assemblies and drawings. With PTC Creo, teams can quickly and accurately create and analyze product designs, including parts, assemblies, drawings, and 3D data. It also allows users to directly share 3D designs with other stakeholders, enabling faster decision-making and improved collaboration. It supports a range of CAD formats, such as CATIA, Pro/ENGINEER, and NX, so users can work with existing product designs. Additionally, PTC Creo includes several features to help users with simulation and analysis, including motion, stress, heat transfer, and fatigue analysis. It also comes with a range of tools to support manufacturing and tooling processes.
Completely software based, where I believe it is mouse based.
Discontinued The project is no longer being developed. The latest version, 1.8.8, released in December 2014, can still be downloaded from the official website.
