The right CAD outsourcing partner saves you time for years. The wrong one costs you rework. These ten questions separate the two before you send a single file.
IN SHORT
- Ask how drawings are checked, who will do your work, and which standards and software they use.
- Get IP protection in writing: an NDA before files, and drawings assigned to you.
- Test with one real drawing before you commit to a larger project.
Most CAD outsourcing problems are predictable. Drawings come back in the wrong standard, nobody checked the dimensions, or every question disappears into a shared inbox. You can avoid nearly all of them by asking the right questions before work starts.
1. How is every drawing checked before it reaches us?
Look for a named checking step where a second engineer, not the person who drew it, reviews each sheet. Ask what the checker looks at: dimensions, tolerances, standards, title block, revision.
2. Who will actually do our work?
You want a named engineer who learns your products and standards, not a different person each time. Ask who your day-to-day contact is and how continuity is handled during leave.
3. Which drawing standards do you work to?
The answer should be: yours. ISO, ASME, DIN or BS, on your title blocks, templates, layers and numbering system.
4. Which software and file versions do you use?
Check they use the same CAD platform and version as you, or can save to it without losing features. A native SolidWorks model is far more useful than a dumb STEP file if you need to edit later.
5. How do you protect our IP?
Ask for an NDA before you send files, how data is stored and who can access it, and confirm that all models and drawings are assigned to you in writing.
6. Have you worked in our industry?
Sheet metal fabrication, pressure vessels, joinery and machine building each have their own conventions. Ask for examples of similar work.
7. How do you quote?
A fixed written quote per project, or a monthly retainer for rolling work, is easier to manage than open hourly billing. Ask what is included, especially revisions.
8. How do revisions and markups work?
Agree how you will send markups, how quickly changes come back, and how revisions are recorded on the drawing.
9. How much of our working day do we share?
Live overlap matters for questions and reviews. Ask how many hours you overlap and whether they cover your morning.
10. Can we start with one drawing?
A confident partner will be happy to prove themselves on a single real drawing. Judge the sheet, the questions they ask and the time it takes.

A quick scorecard
| QUESTION | GOOD ANSWER | WARNING SIGN |
|---|---|---|
| Checking | Second engineer checks every sheet | "Our designers are very careful" |
| Contact | Named engineer | Shared inbox, rotating staff |
| Standards | Yours: ISO, ASME, DIN or BS on your templates | Their own house style |
| IP | NDA first, IP assigned in writing | NDA after files are sent |
| Pricing | Fixed written quote or retainer | Open-ended hourly rate |
| Trial | Happy to start with one drawing | Minimum contract up front |
Questions people ask
What should I look for in a CAD outsourcing company?
A formal checking process, a named engineer, drawing to your standards, the right software, IP protection in writing, relevant industry experience and clear fixed pricing.
Should I test a CAD outsourcing partner first?
Yes. Send one real, representative drawing. It shows accuracy, standards, communication and turnaround far better than a sales call.
What contract terms matter most?
An NDA signed before files are shared, written assignment of all IP to you, clear scope and revision terms, and a fixed price or agreed retainer.
Is hourly or fixed pricing better for CAD outsourcing?
Fixed written quotes are easier to budget and compare. A monthly retainer suits rolling work. Open hourly billing makes the final cost hard to predict.
