CAD and Drawing Submission Guide for Your RFQ
Send a drawing package that lets your supplier quote your required process, quantity and inspection scope in one pass.
What to include in your quote package
| File or information | What to provide | Why buyers need it |
|---|---|---|
| 3D model | STEP or another supported CAD format, with units and revision | Communicates geometry and helps the supplier review access. |
| Controlled drawing | PDF with revision, material, finish and critical callouts | Defines what to manufacture and inspect. |
| Quantity and destination | Sample and repeat quantities, destination and target timing | Allows comparison at the same volume and delivery scope. |
| Inspection scope | Required records, first article checks and approval contact | Makes evidence and approval work visible in the quote. |
Use these examples to prepare your request. Confirm stock and acceptance criteria for your project.
Before you send your RFQ
- For your CNC machining RFQ, confirm the 3D model and PDF represent the same revision.
- If files disagree, identify the controlling document and resolve the discrepancy before releasing work.
- Ask for an NDA before sending sensitive files. Include the mating part or a redacted interface drawing if fit depends on it.
