It is used to exchange data between CAD and CAM and also to exchange information between different CAD systems. Two formats have become widely established for this: <strong>STEP</strong> as a vendor-neutral standard and <strong>X_T</strong> through the widespread use of the Parasolid kernel.</p> <figure class="diagram"> <svg viewBox="0 0 720 96" width="720" role="img" aria-label="Process chain: CAD, CAM, postprocessor, NC code, CNC machine" xmlns="http://www.w3.org/2000/svg"> <defs> <marker id="pc-arrow" markerWidth="8" markerHeight="8" refX="7" refY="4" orient="auto"> <path d="M0,0 L8,4 L0,8 Z" class="d-arrowhead"/> </marker> </defs> <rect x="4" y="18" width="120" height="60" rx="9" class="d-box-accent"/> <text x="64" y="44" text-anchor="middle" class="d-text-accent">CAD</text> <text x="64" y="63" text-anchor="middle" class="d-text-small">design</text> <path d="M128 48 H150" class="d-arrow" style="marker-end:url(#pc-arrow)"/> <rect x="152" y="18" width="120" height="60" rx="9" class="d-box"/> <text x="212" y="44" text-anchor="middle" class="d-text">CAM</text> <text x="212" y="63" text-anchor="middle" class="d-text-small">programming</text> <path d="M276 48 H298" class="d-arrow" style="marker-end:url(#pc-arrow)"/> <rect x="300" y="18" width="120" height="60" rx="9" class="d-box"/> <text x="360" y="44" text-anchor="middle" class="d-text">Postprocessor</text> <text x="360" y="63" text-anchor="middle" class="d-text-small">translation</text> <path d="M424 48 H446" class="d-arrow" style="marker-end:url(#pc-arrow)"/> <rect x="448" y="18" width="120" height="60" rx="9" class="d-box"/> <text x="508" y="44" text-anchor="middle" class="d-text">NC-Code</text> <text x="508" y="63" text-anchor="middle" class="d-text-small">G-code</text> <path d="M572 48 H594" class="d-arrow" style="marker-end:url(#pc-arrow)"/> <rect x="596" y="18" width="120" height="60" rx="9" class="d-box"/> <text x="656" y="44" text-anchor="middle" class="d-text">CNC machine</text> <text x="656" y="63" text-anchor="middle" class="d-text-small">machining</text> </svg> </figure> <h2 id="step--stp-file">STEP / STP file</h2> <p>The STEP format (Standard for the Exchange of Product Data) is an industrial file format for exchanging 3D models and product information between different CAD systems.
