FreeCAD is a customizable, open-source paramentic 3D CAD and BIM software with FEM support, built on the Opencascade geometric kernel. It was created primarily for product design and mechanical engineering, but it can be used in a wide range of industries, such as electrical engineering, or architecture. It runs on Windows, Mac OS, and Linux.
FreeCAD is made to craft real-life objects of different sizes and is perfect for a home user/amateur, programmer, experienced CAD software user, or educator. This software provides tools similar to those of SolidWorks, Catia or Autodesk Revit.
Teamcenter by Siemens is a product lifecycle management (PLM) suite originally created by UGS Corporation. It allows companies to optimize the product development process across all departments and stakeholders.
The system enables BOM and MS Office documents management, change management, and CAD systems integration on-premises and on-cloud. Mechanical, electrical, and software information is all stored in Teamcenter.
A CAD file is an output of a CAD software, containing key information about the designed object: its geometry and topology representation, 3D model hierarchy, metadata, and visual attributes depending on the format of the file.
