Customer sent a STEP file but no drawing — what tolerance do I quote?
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.
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.

The direct answer
For a 50 mm pocket, a stated ±0.005 inch default may suit a rough bracket but not a bearing seat. Put the default beside the model revision and price later inspection or rework risk explicitly.
Test the decision against the shop evidence in this example: For a 50 mm pocket, a stated ±0.
Carry the measurable input from the worked case into the estimator's notes: For a 50 mm pocket, a stated ±0.
Evidence from a shop floor
The same fictional bracket is $464.53 for one and $83.77 each at ten under the pricing model’s nominal model assumptions; that result is not an acceptance guarantee. Request the drawing or written approval before releasing a firm quote, especially for fits, pressure boundaries, or safety features.
Keep the commercial decision tied to the evidence, including for a 50 mm pocket, a stated ±0.
The handoff is complete only when the owner can restate the route without losing for a 50 mm pocket, a stated ±0.
Build the quote route
List model revision, units, missing datums, assumed general tolerance, critical features, inspection method, and approval owner before programming.
A useful review question is whether the current RFQ still matches this route: list model revision, units, missing datums, assumed general tolerance, critical features, inspection method, and approval owner before programming.
The next estimator should be able to challenge the assumption behind this route: list model revision, units, missing datums, assumed general tolerance, critical features, inspection method, and approval owner before programming.
Use the source notes to date the assumption and record why this route was selected: list model revision, units, missing datums, assumed general tolerance, critical features, inspection method, and approval owner before programming.
Release and learn
A STEP model carries nominal geometry; it does not prove material, finish, datum scheme, thread class, or functional tolerance.
If the buyer asks for a different outcome, explain the boundary in these terms: a step model carries nominal geometry; it does not prove material, finish, datum scheme, thread class, or functional tolerance.
Before changing the total, verify whether the caveat applies: a step model carries nominal geometry; it does not prove material, finish, datum scheme, thread class, or functional tolerance.
A customer-facing explanation should make the risk legible: a step model carries nominal geometry; it does not prove material, finish, datum scheme, thread class, or functional tolerance.
Close the loop by noting the evidence that would make this estimate obsolete: a step model carries nominal geometry; it does not prove material, finish, datum scheme, thread class, or functional tolerance.
Keep the commercial decision tied to the evidence, including for a 50 mm pocket, a stated ±0.

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
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.

Do fab shops price weldments by the pound, and does it work?
Use $/lb only as a calibrated screen for a stable family; cut, fit-up, weld length, grinding, finish, and installation decide the final price.
