What matters most before you upload.

Use this page to answer the sourcing question in front of you, then carry that answer back into the quote flow with the right file and the right expectations.

What to check first

Before you upload, make sure the file and part state match the manufacturing route you actually expect.

  • Use a flat file only when the part is meant to stay flat.
  • Use a formed STEP when bend count, flange lengths, or shape inspection matter.
  • Do not flatten a bent part just to force it through the laser path if the job is really formed.

What changes the quote

These are the practical factors that usually move cost, routing, or review outcome.

  • Flat files drive cut pricing and material selection cleanly.
  • Formed models add weight, bend count, and brake-fit logic.
  • The file type changes what the customer can preview and validate before checkout.

How to turn the advice into the next action.

The point of the article is not just to explain the topic. It is to help you decide what to upload, what to compare, and what to expect next.

How this connects to the quote tool

The live quote flow still matters because it shows the cost impact of the decisions you are weighing.

  • Flat parts route differently from formed parts.
  • Material, thickness, and quantity still drive the final number.
  • Review messages are part of the buying logic, not a dead end.

When review is normal

A good article should help buyers recognize when review is the right answer instead of being surprised by it.

  • Large, heavy, or unclear formed parts often need review.
  • Messy or mismatched files can slow even simple jobs down.
  • The safest quote is the one that matches the real part and the real process.
