    Which CAD files should you send for a sheet metal quote?

    STEP, DXF, STL and PDF each solve different parts of a quote request. The best package combines machine-readable geometry with clear manufacturing requirements.

    STEP is the best base for 3D parts

    For bent parts and assemblies, STEP carries topological 3D geometry that can be measured: solids, faces, edges, holes and radii.

    A STEP file still needs business and manufacturing context such as quantity, material, tolerances, finish and delivery requirements.

    DXF works for flat cutting

    DXF can be enough for flat parts with closed contours, but material and thickness must be supplied separately. It is less suitable when bending, holes with depth or assemblies matter.

    PDF is a requirement document

    A drawing is valuable for tolerances, notes and finish requirements, but it forces more manual interpretation. Pair it with CAD geometry when speed and traceability matter.

    Geometry Viewer reads identified requirements from the PDF drawing, such as material, tolerances, surface requirements and weld symbols, and collects them for the estimator's review. Not everything in a drawing can be interpreted, so the original drawing is always part of the review.
