CATIA is a multi-platform software kit for CAD/CAM/CAE, PLM and 3D, created by the French company Dassault Systèmes.

Commonly referred to as a 3D PLM software suite, CATIA supports all stages of product development, including conceptualization, design, engineering and manufacturing. CATIA facilitates collaborative engineering across disciplines around its 3DEXPERIENCE platform, including surfacing & shape design, electrical, fluid and electronic systems design, mechanical engineering and systems engineering. CATIA facilitates the design of electronic, electrical, and distributed systems such as fluid and HVAC systems, all the way to the production of documentation for manufacturing.

Tekla, owned by Trimble is a software product family that consists of programs for analysis and design. Tekla software includes several applications.

Tekla Structures is 3D BIM software widely used in the building and construction industries. The software allows users to create and operate 3D structural models in concrete or steel and leads them through the process from concept to fabrication.

Tekla Structural Designer is a software app for analysis and construction design. It is used by structural engineers.

Tekla Tedds is a software solution for automating repetitive calculations. It is used in engineering for creating output such as calculations, sketches and notes.

Tekla BIMsight is an application for building information model-based construction project collaboration.
