What to Do When DFM Flags Your Part

When DFM flags your part, do not re-upload the same file. Read each flag on a named face, then change CAD, change the note, or accept the risk. Upload CAD.

What to Do When DFM Flags Your Part

What Should You Do When DFM Flags Your Part?

This page answers what to do when dfm flags your part after the definition page has already named the note. Read each flag against a named face, then choose change the solid, change the requirement, or accept the note. A flag is not the end of the quote.

The next step is a new package with that decision written down. For definitions, read what DFM flags mean on an instant quote. This page is the action list.

Key Facts

  1. Every flag needs one of three answers: change CAD, change the RFQ, or accept.
  2. Do not ignore a flag and send the same file again.
  3. If the solid changes, re-quote as a new revision.
  4. If only the note changes, keep the same revision ID and say so.
  5. Reviewers confirm accepted flags before tooling release.
  6. No wall, draft, or gate numbers appear on this page.
  7. Upload the next package on the injection molding instant quote platform.

Decide on Each Flag

A flag is not a stop sign. It is a dropdown: change CAD, change note, or accept.

Change CAD: the solid created the risk

Change CAD when the solid created the risk: draft, wall, boss, or rib. Name the face. Do not write we will look at DFM.

Change the RFQ: the requirement was tighter than the face can hold

Change the RFQ when the requirement was tighter than the face can hold. Move the tight band, drop the grain, or loosen the note. The solid can stay.

Accept the risk: write it on the face

Accept when the face can live with the note and you write that down. We accept DFM closes nothing. Accept scuff on non-show face A closes one.

Do not mix three flags into one sentence. A reviewer cannot confirm a bundle. One face, one decision.

Send the Next Package

Note-only change: same revision ID, new quote record

If you only changed a note, say same revision, note update in the new record. Keep the CAD revision ID. The new record is history, not an overwrite.

Solid changed: new revision ID, then re-quote

If the solid moved, bump the revision ID and follow how to re-quote after a CAD revision. Mixing note-only and solid-change cases is how sourcing loses the thread.

One face, one decision. A bundle is not reviewable

One face, one decision. A bundle is not reviewable. Accepted risk on a scoped program may still need when an instant quote needs engineering review.

Point to injection molding DFM review if you need the review program, not another flag definition.

RFQ Checklist

Numbered steps:

  1. List each flag and the face it names.
  2. Write accept, CAD change, or requirement change.
  3. Export a new revision if the solid moved.
  4. Attach the same 2D revision or mark 2D pending.
  5. Upload CAD through the injection molding instant quote platform.

If step 2 is blank, stop. Same file, no decision equals the same flag with a new timestamp.

A Worked Example

Three flags come back: a texture wall, a logo boss, and a tight band on a long clip. The team writes one sentence: we accept DFM. That sentence closes nothing.

Split the list. Texture wall: add draft, keep the grain. Logo boss: core the mass. Clip band: move the tight requirement to the seal face only. Three lines, three actions. Export a new revision for the wall and the boss. Keep the same revision if you only moved the band in notes, or bump it if the clip solid changed. Upload. Review now has decisions.

If a teammate disagrees on the clip band, write the disagreement on that face. Do not leave the flag blank.

Common Mistakes

Sending the same file again with no decision.

Accepting flags in a meeting and never writing them on the quote.

Changing CAD for one flag and hoping the other two disappear.

Asking sourcing to ignore a flag because the first click already had a number. The number was tied to the unanswered flag.

What to Tell Sourcing

The next step is a written decision per flag, then a new upload. The quote is not dead. It is waiting on accept, CAD change, or requirement change.

If they want a date, the date is when those decisions are written and the next package is uploaded. A meeting without written decisions does not close flags.

If they disagree with a flag, write the disagreement on the named face. That is a review item. Silence is not a disagreement. It is a repeat.

Send the next package through the instant quote platform so the decision and the flag sit on one record.

Frequently Asked Questions

What should I do when DFM flags my part?

Read each flag against a named face, then choose change the solid, change the requirement, or accept the note. A flag is not the end of the quote. The next step is a new package with that decision written down.

Can I accept every flag and still cut steel?

You can accept flags you understand and write down. Reviewers confirm accepted flags before tooling release. Accepting a flag that changes steel scope can still move the next quote. Do not accept a note you have not read.

Do I re-quote if I only change a note?

Yes, as a new record if you want a clean history, and keep the same CAD revision ID. Say that only the note changed. If the solid moved, use a new revision ID and follow the re-quote steps.

How do I write an accepted DFM risk so it survives to T1 and inspection?

Write the face name, the risk, and the acceptance in the RFQ or on the 2D, for example non-show face A: accept sink on a painted face. Do not leave it in chat. Reviewers confirm accepted flags before tooling release, and the inspection plan should reference the same written note so first-article review does not reopen a decision nobody recorded.

A DFM flag sits on one body of a family tool or overmold. How is that tracked?

Name the body in the decision. Logo boss on body A: core the mass is trackable. Fix the DFM is not. Each flagged body gets its own accept, CAD-change, or requirement-change line, and the re-quote notes which bodies moved and which kept the same revision.

What if I disagree with a flag?

Write the disagreement against the named face and why. Upload the same solid with that note. A silent ignore looks like the same package. A written disagreement is a review item.

Who sees the decision before tooling release?

Engineering review sees the accept or change note on the quote record. The decision has to live on that record. A chat message that never reaches the RFQ is not a decision.

Ready to quote

Ready to validate your design?

Upload your CAD. Reviewers can flag DFM notes and return pricing on the same package. Got flags? List each face, pick change-CAD, change-note, or accept, and upload the next package. Reviewers confirm accepted risks before steel, so first-article review asks whether the steel matches the decision, not what the team decided.
