STEP in het kort
STEP
Convert to STEP when the output is intended for engineering exchange between CAD systems, suppliers, manufacturing partners, or PLM workflows.
It is the right target for precise solid models and product data that must survive outside a single vendor's toolchain.
Choose STEP when engineering fidelity and interoperability matter more than lightweight visualization.
IGES in het kort
IGES
Convert to IGES when the receiving engineering system or supplier workflow still expects that neutral geometry format, particularly for curves and surface-focused CAD exchange.
It is useful for legacy interoperability and long-lived manufacturing relationships.
For newer product-model exchange with richer semantics, STEP is often the better choice.

What changes when converting STEP to IGES?
This conversion changes how the format behaves in downstream tools and delivery environments.
What should I review after converting STEP to IGES?
