    What should a sheet metal quoting system read from a STEP file?

    A STEP file is the technical basis of a quote, but it is not the whole quote. A good system separates measurable geometry from assumptions, rules and human approval.

    Start with measurable geometry

    The system should read solids, surfaces, edges, holes, cutouts, bends and possible weld indications directly from the model. The estimator should be able to inspect what was found and trace each cost driver back to geometry.

    This matters because a faster quote is only useful when the decision can still be explained to a customer or production planner.

    Keep CAD, AI and review separate

    Deterministic CAD analysis should measure the file. AI can structure the RFQ email and suggest missing data, but it should not invent dimensions or change geometry.

    Material grade, quantity, tolerances, finish and delivery requirements still need to come from the request, the drawing or an approved manual choice.

    Turn the file into a traceable calculation

    Cut length, pierces, bends, blank size and secondary operations become useful only when they are connected to your own machines, speeds, setup times and margin rules.

    That is why Glintify calibrates the calculation to each manufacturer instead of using an anonymous industry average.

    Test with one of your own STEP files

    Bring a historical quote and we will show which geometry can be measured, what needs review and how the cost basis can be traced.
