Upload CAD for quote
Upload CAD Files for Custom Metal Parts Quote Review
Upload CAD files, controlled drawings, and RFQ details in one engineering-ready package for prototypes, pilot runs, and repeat low-volume metal programs. Great Material uses the submitted file package to review process route, metal grade, finish, critical tolerances, inspection scope, destination, and NDA handling before preparing the quote response.
Use the form to define process, metal grade, quantity, finish, critical tolerances, required inspection documents, destination country, and NDA status before the review starts. If the project still needs route comparison, review custom metal parts or CNC machining services first.
Teams looking for an upload CAD quote, upload drawing for quote, or request a quote machining workflow usually need the same thing: one engineering RFQ form that captures geometry, process, material, quantity, finish, and documentation before pricing starts.
Process, material, finish, tolerance
Inspection docs, destination, NDA
This machining quote form also works as an engineering RFQ form for prototype, pilot, and repeat-supply packages, including mixed-process uploads that need a CAD upload machining RFQ review before commercial release.
Accepted files
STEP, STP, IGES, IGS, X_T, SLDPRT, PDF drawings, and ZIP packages.
RFQ fields
Process, material, quantity, finish, critical tolerance, and target lead time.
Quality notes
Dimensional report, FAI, CoC, and material-cert requests belong in the first submission.
Buyer context
Destination country, packaging notes, revision status, and NDA requirement.
What to upload before engineering review starts
The best RFQ packages include both geometry and decision context. CAD explains shape, but the drawing still controls thread notes, datums, finish calls, inspection points, and revision status. Buyers who state these items early usually avoid the slowest clarification loops. A CNC quote upload drawing package should make those controls visible in the first submission.
- 3D model plus latest 2D drawing: use both whenever the part has critical fits, threads, surface notes, or inspection points.
- Material by part number: separate the metal grade for each item when the RFQ includes multiple components.
- Finish or cosmetic notes: define anodizing, passivation, blasting, coating, or protected surfaces before the quote is released.
- Critical dimensions and quality scope: call out fit surfaces, special tolerances, FAI, dimensional reports, or material-cert needs.
- Commercial context: include target lead time, destination country, packaging notes, and NDA status in the first handoff.
For a cleaner drawing package, review RFQ drawing requirements. For projects still comparing routes, review custom metal parts and surface finishing.
RFQ package completeness matrix
Each quote line changes when process route, metal grade, finish, document level, or program stage changes. Use this matrix to reduce avoidable clarification rounds before the quote review begins.
| RFQ input | Examples | Why it changes the quote |
|---|---|---|
| File package | STEP, STP, IGES, X_T, SLDPRT, PDF, ZIP | determines whether geometry, revision notes, and controlled requirements are complete |
| Process route | milling, turning, sheet metal, mixed-process package | changes machine path, fixturing, and how the part family is reviewed |
| Metal grade | 6061, 7075, 304, 316, 4140, C360, Ti-6Al-4V | changes machining behavior, finish compatibility, tool wear, and certification needs |
| Finish requirement | anodizing, passivation, blasting, coating, black oxide | changes masking, cosmetic review, packaging, and lead time |
| Inspection-document level | dimensional report, FAI, CoC, material certs | changes planning, traceability, and final acceptance steps |
| Program stage | prototype, pilot run, repeat low-volume | changes revision control, packaging logic, and expected documentation depth |
Quote-ready submission checklist by file type
Top RFQ platforms make upload fast, but manufacturer review still depends on whether the file package explains geometry, drawing controls, quantities, documentation scope, and security expectations. Use this checklist when preparing a multi-part CAD upload or controlled drawing package. When buyers search for an upload CAD for quote workflow, they still need the same review detail behind the form.
| Upload item | Best file or form field | Engineering reviews | Common issue avoided |
|---|---|---|---|
| 3D CAD model | STEP, STP, IGES, X_T, SLDPRT | geometry, stock size, process route, fixturing risk, and feature access | quoting from screenshots, incomplete exports, or outdated model revisions |
| 2D controlled drawing | PDF with revision, title block, and date | threads, datums, critical tolerances, surface finish notes, and inspection points | missing callouts that change manufacturing time or inspection scope |
| Part list or BOM | spreadsheet, ZIP folder naming, or project notes | part numbers, quantities, material per item, finish per item, and program stage | mixing different materials, finishes, or quantities inside one quote line |
| Inspection request | inspection document field and project notes | FAI, inspection report, dimensional report, CoC, material certificate, and traceability needs | adding document scope after the price and lead-time review has started |
| Security or NDA note | NDA field plus project notes | confidential file handling, restricted distribution, and review path expectations | unmarked security expectations after sensitive files are already submitted |
What happens after you submit
A transparent review path helps buyers understand that the submission enters an engineering and documentation review, not a generic inbox. It also makes clear why incomplete RFQs can slow down pricing.
| Review step | What gets checked |
|---|---|
| 1. File and revision check | format, completeness, latest revision, and whether the package matches the intended part numbers |
| 2. Route selection | milling, turning, sheet metal, or mixed-process handling for the submitted items |
| 3. Material and finish review | metal grade, finish compatibility, visible faces, masking, and corrosion or wear expectations |
| 4. Documentation planning | dimensional reports, FAI, material certs, packaging notes, destination, and NDA handling |
| 5. Quote response preparation | commercial response based on the actual manufacturing and document scope |
If documentation is the main concern, review quality control and material certificates and traceability.
If your buyer workflow starts with a CAD upload machining RFQ, add the required inspection report level, material cert option, and destination notes before submit so the first quote round reflects the real acceptance scope.
Prototype, pilot, and repeat supply need different inputs
Prototype RFQs can be lighter, but pilot and repeat-supply RFQs need stronger revision control, document planning, and acceptance notes. Match the submission to the program stage so engineering review receives the right level of detail.
| Program stage | Best submission detail |
|---|---|
| Prototype | CAD, latest drawing, material intent, function-critical dimensions, target quantity, and delivery timing |
| Pilot run | final revision control, cosmetic notes, finish callouts, inspection level, and packaging direction |
| Repeat low-volume | approved drawings, quantity bands, repeat cert expectations, destination details, and stable commercial notes |
Final buyer checklist before submission
Before you upload, confirm the package already answers the most common quote blockers.
- the file set is complete and the latest revision is clear
- material is assigned per item
- finish is declared where it affects price or cosmetics
- critical dimensions, threads, and fit surfaces are visible on the drawing
- inspection-document requests are included
- target lead time, destination country, and packaging notes are stated
- NDA handling is selected when required
That combination is what turns a generic file drop into an engineering-ready custom metal parts quote package instead of a partial request that still needs several clarification loops.
