CATIA Scripts enable engineers and designers to automate modeling, drafting, and assembly operations.

They reduce manual effort in repetitive design tasks and improve productivity.

Scripts can access CATIA’s API to manipulate geometries, parts, assemblies, and drawings programmatically.

They support batch processing, parameterization, and customization of the CATIA environment.

Facilitate integration with PLM systems, databases, and external applications for enhanced workflow.
