CATIA automation via Python scripts

Automate CATIA with Python – Generate Simulation-Ready Geometry for CAE and FEA

Stop wasting hours on repetitive modeling tasks in CATIA. Learn how to automate geometry creation, sketching, and part design using Python, and unlock the full power of one of the world’s leading CAD platforms.

This course shows you how to streamline your CATIA workflows, reduce errors, and create simulation-ready geometries for use in CAE and FEA software such as ANSYS Mechanical, Abaqus, SIMULIA, Altair HyperMesh, MSC Nastran, Siemens Simcenter, and Autodesk Inventor Nastran. You’ll also learn how to generate CATIA outputs for CFD tools like STAR-CCM+, Fluent, and OpenFOAM for end-to-end simulation automation.

No Visual Basic or Excel macros required — this course focuses exclusively on Python, the most versatile and accessible scripting language in engineering automation.
