How would you automate repetitive design tasks in CATIA using VBA scripting?

CATIA automation with VBA involves: accessing the CATIA object model through Application > Documents > Part > Bodies > Shapes hierarchy, using Selection object for interactive workflows, implementing error handling for geometry failures, creating parametric features through HybridShapeFactory, managing design tables through ExcelAutomation, and integrating with external databases for standard parts. Example: automated hole pattern creation loops through spreadsheet coordinates, creates hole features with proper references, and updates model parameters. Best practices include modular code structure, logging, and user interface through UserForms for input validation.
