Design Automation in Closure Engineering: Building Parametric Assemblies With CATIA and VB Scripting

Modern closure systems in EVs and advanced vehicles demand more than just clean geometry; they require embedded logic, constraint-driven structures, and validation-aware modeling. While CATIA V5/V6 offers robust 3D capabilities, its true power emerges when engineers start treating CAD like code. With VB scripting, it is possible to encode design intelligence directly into the CAD model, enabling parametric automation across complex mechanical assemblies.

This article breaks down how parametric automation can reduce review-cycle fatigue, enforce design intent, and enable a traceable, simulation-ready closure workflow.
