What is CATIA CAD Software

CATIA stands for Computer Aided Three-Dimensional Interactive Application. It is developed by Dassault Systèmes and is widely used by engineers and designers to create 3D models and product designs. With CATIA, engineers can:

• design mechanical parts
• create product assemblies
• build complex surfaces
• generate manufacturing drawings

CATIA allows engineers to visualize products in a 3D environment before manufacturing, which helps reduce design errors and improve product quality.
