STEP at a glance
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.
