Computer Aided Three-Dimensional Interactive Application supports multiple stages of product development from conceptualization, design, manufacturing and engineering. The major facilities provided by CATIA include:

• A suite for surfacing, reverse engineering and visualizing solutions to create, modify and validate complex innovative shapes
• The ability to create 3D parts out of sheet metal or composites, as well as molded, forged or tooling parts and mechanical assembly definitions
• Tools to complete product definitions including functional tolerance and kinematics definitions
• The facility to design electronic, electrical and distributed systems such as fluid systems, and heating, ventilation and air conditioning systems
• Solutions for modeling complex and intelligent products through a systems engineering approach
• A systems engineering approach that covers the requirements definition, systems architecture and embedded software generation and behavior modeling
• Customization through application program interfaces
