How do I quote a part from a sample or a broken part (reverse engineering)?
Price one of your own parts: Drop a STEP model or PDF drawing — about 90 seconds, no account.
Your part priced in about 90 seconds, no account.
Charge measurement, modeling, drawing, and verification as NRE before quoting the replacement machining.

The direct answer
A broken sample may need $240 measurement and modeling, $85 drawing review, and $310 machining. Make reverse-engineering work a visible gate before promising interchangeability.
Test the decision against the shop evidence in this example: A broken sample may need $240 measurement and modeling, $85 drawing review, and $310 machining.
Carry the measurable input from the worked case into the estimator's notes: A broken sample may need $240 measurement and modeling, $85 drawing review, and $310 machining.
Evidence from a shop floor
Measurement $142.50 + modeling $275 + drawing $95 + workholding $35 + one-piece engine machining $464.53 = $1,012.03. Agree the reverse-engineering deliverable, fit responsibility, sample condition, and CAD ownership before measuring.
Keep the commercial decision tied to the evidence, including a broken sample may need $240 measurement and modeling, $85 drawing review, and $310 machining.
The handoff is complete only when the owner can restate the route without losing a broken sample may need $240 measurement and modeling, $85 drawing review, and $310 machining.
Build the quote route
Define what is measured, what is inferred, who approves the reconstructed drawing, and which features require fit or functional testing.
A useful review question is whether the current RFQ still matches this route: define what is measured, what is inferred, who approves the reconstructed drawing, and which features require fit or functional testing.
The next estimator should be able to challenge the assumption behind this route: define what is measured, what is inferred, who approves the reconstructed drawing, and which features require fit or functional testing.
Use the source notes to date the assumption and record why this route was selected: define what is measured, what is inferred, who approves the reconstructed drawing, and which features require fit or functional testing.
Release and learn
Wear, damage, and unknown material condition can make a sample an unreliable authority; record uncertainty.
If the buyer asks for a different outcome, explain the boundary in these terms: wear, damage, and unknown material condition can make a sample an unreliable authority; record uncertainty.
Before changing the total, verify whether the caveat applies: wear, damage, and unknown material condition can make a sample an unreliable authority; record uncertainty.
A customer-facing explanation should make the risk legible: wear, damage, and unknown material condition can make a sample an unreliable authority; record uncertainty.
Close the loop by noting the evidence that would make this estimate obsolete: wear, damage, and unknown material condition can make a sample an unreliable authority; record uncertainty.
Keep the commercial decision tied to the evidence, including a broken sample may need $240 measurement and modeling, $85 drawing review, and $310 machining.

Answers
Can I ship 10% more or fewer parts than ordered?
Only when the purchase order or customer has agreed a quantity tolerance; there is no universal right to ship ten percent extra or short.
Answers
Can I use Xometry or Protolabs instant quotes as a price check?
Use an instant quote as a dated comparison point after matching quantity, revision, finish, inspection, freight, and delivery scope; it is not a neutral market index.
Answers
Customer sent a STEP file but no drawing — what tolerance do I quote?
Use a written model-only default only when the customer accepts it; a practical example is to model with ±0.005 inch unless a drawing states otherwise, while calling out material, finish, threads, and inspection as open.
Answers
Customers make us re-enter quotes in their supplier portals — how do other shops handle it?
Treat portal re-entry as measurable quote administration: export the approved quote, time the work, and decide whether the effort is included or charged.
