What are the key differences between SolidWorks and CATIA?

SolidWorks is a mid-range CAD tool ideal for small to medium assemblies with an intuitive interface and lower learning curve, commonly used in general manufacturing. CATIA is an enterprise-level CAD/CAM/CAE solution used for complex surface modeling (aerospace, automotive), large assemblies, and integrated PLM workflows. CATIA offers advanced surfacing, kinematics, and multi-disciplinary design capabilities but requires more training.
