How to Re-Quote After a CAD Revision
What Does It Mean to Re-Quote After a CAD Revision?
This page answers how to requote after a cad revision when the solid moved and someone still wants the old number. A re-quote is a new instant estimate against a new solid, or against the same solid with updated RFQ fields. Keep the quote reference tied to the CAD revision ID so two numbers can be compared.
The old quote stays as history. It is not a price lock. For causes, read why instant quote changes after CAD review. This page is the method.
Key Facts
- Upload the new revision. Do not overwrite notes on an old file and hope the number updates.
- Update material, quantity, finish, or tolerance fields only when they changed.
- Leave unchanged fields identical so the delta is the solid.
- Write both quote IDs and both revision IDs in your comparison table.
- A DFM flag on the new solid is a new decision, not a carry-over. See what DFM flags mean on an instant quote.
- No prices or lead times appear on this page.
- Upload the new package on the injection molding instant quote platform.
When to Re-Quote
Solid changed: new revision ID, new record
The solid changed. Export a new revision ID and open a new quote record. If the design is still moving, read quote before design is final. The old record stays as history.
Units or scale fixed: same geometry, different file truth
Units or scale were wrong on the first export. That is a new package even if the part looks the same. Write that the revision intent is a format or units fix so sourcing does not treat it as a design change.
RFQ fields completed after first click: same solid, new assumptions
RFQ notes were completed after the first click. Same solid, new assumptions. That is still a new record. Copy the solid, then change only the field that was empty.
Isolate One Variable
Record A: baseline revision and baseline RFQ
Keep the last accepted package as the baseline. Do not edit it in place.
Record B: new solid, old RFQ fields copied
Upload the new solid. Copy material, quantity, finish, and tolerance fields from Record A. That delta is the solid.
Record C: new solid, new quantity only
If quantity also changed, do not fold it into Record B. Open Record C on the same new solid and change quantity only. If you change CAD and quantity together, you bought a blended delta you cannot defend.
When Not to Compare Two Quotes
Different revision and different quantity are two programs
Different revisions and different quantity fields at once are two programs. Split the comparison or you will argue the wrong delta.
One has 2D balloons, the other does not
One quote has 2D notes and the other does not. Attach the matching 2D if balloons moved. See when 2D drawing is required.
Old DFM flags carried over without a yes or no
A DFM flag on the new solid is a new decision. Silent carry-over is how a closed note reappears. Read what DFM flags mean on an instant quote.
RFQ Checklist
Numbered steps:
- Export the new solid with a new revision ID.
- Copy RFQ fields from the last quote, then edit only what changed.
- Attach the matching 2D if balloons moved.
- Record old quote ID, new quote ID, and both revisions.
- Upload CAD through the injection molding instant quote platform.
If you skip step 2, the new quote is not a controlled experiment. Sourcing will not trust the delta.
A Worked Example
Revision D adds a snap. The buyer also fixes annual quantity from a planning band to a single number in the same session. The new quote moves. Sourcing asks if the snap is expensive. Nobody can tell. The quantity changed too.
Do it again. Re-quote revision D with the old quantity fields copied exactly. That delta is the snap. Then, if needed, re-quote the same revision D with the new annual number. That delta is the forecast. Two records, two causes.
Write the table: quote 1 revision C, quote 2 revision D same quantity, quote 3 revision D new quantity. The meeting gets shorter.
Common Mistakes
Editing the old record in place and erasing history.
Changing CAD, material, and quantity on one re-quote and asking for a single explanation.
Forgetting the 2D when balloons moved with the solid.
Leaving DFM flags from revision C on the revision D notes without saying whether they still apply.
What to Tell Sourcing
A re-quote is a new record. Keep the old one. Bring both IDs and both revision IDs. If they want one delta, change one variable.
If they changed CAD and quantity together, do it again as two records. That is faster than arguing a blended delta for an hour.
If they ask to edit the old quote in place, say no. History is the explanation.
If flags existed on the last revision, say whether each one still applies. Silent carry-over is how closed notes reopen.
