Learn CATIA-SCRIPTS with Real Code Examples
Updated Nov 27, 2025
Architecture
CATIA application exposes APIs accessible via scripting languages
Scripts interact with document objects (Part, Product, Drawing)
Macros can be triggered manually, via events, or in batch mode
Data can be read from or written to external sources (Excel, databases)
Scripts can modify geometries, assemblies, or annotations programmatically
Rendering Model
Scripts interact with CATIA documents (Part, Product, Drawing)
Geometries and assemblies are manipulated programmatically
Parameters drive dimensions and design variants
Batch scripts execute operations on multiple documents
PLM/ERP integration synchronizes data externally
