CATIA: high-end
Complex surfacing, large assemblies, automotive and aerospace.
Comparison中文
CATIA vs SolidWorks
CATIA and SolidWorks are both Dassault Syst\u00e8mes products, but they target different needs. CATIA is a high-end system for automotive, aerospace and complex surfacing, while SolidWorks is a mainstream mechanical design tool favored for its accessibility.

SolidWorks: mainstream
Approachable mechanical design used broadly across industry.
Exchange via STEP
Both export to STEP for cross-CAD collaboration.
How to choose
CATIA suits organizations needing advanced surfacing and very large, complex assemblies, often in automotive and aerospace.
SolidWorks suits teams wanting a fast, accessible mechanical design tool with a large ecosystem.
Exchanging files between them
Native CATIA and SolidWorks files are not directly interchangeable, so STEP is the common neutral bridge.
You can convert CATIA to STEP or SolidWorks to STEP, then import into the other system.
