Why STEP Files Go to Manual Review: a practical quoting checklist.

Checks before quoting why step files go to manual review

  • Verify the model is either truly flat or truly formed, not a placeholder in between.
  • Check whether the part is longer, heavier, or more complex than the online rules support.
  • Make sure the model has a believable thickness and a clear finished shape.

Cost and review factors for why step files go to manual review

  • Long bends or high tonnage push formed parts out of the instant path.
  • Ambiguous geometry can make bend or wall detection unreliable.
  • Out-of-range thickness or blank size can move the part into review even if the model is clean.

Next actions for why step files go to manual review

  • Use review as the right path for edge cases instead of forcing a bad instant quote.
  • If the part is actually flat, upload it so it can route as a laser-cut part.
  • When the geometry is solid, keep the model simple and representative.
