STEP

STEP (ISO 10303) is the global standard for exchanging 3D CAD models and product data across different engineering software.

Engineers waste too much time translating files between incompatible software. STEP (Standard for the Exchange of Product Model Data) solves this by acting as a universal translator for 3D designs, assemblies, and manufacturing specifications. Officially designated as ISO 10303, this neutral format preserves precise geometry and critical metadata throughout a product's lifecycle: from initial design to the factory floor. By bypassing proprietary file locks, STEP keeps global supply chains moving without costly data loss.
