Drawing to STEP
- Fully automated
- Free quote
- Quality report
Upload a PDF or image of an engineering drawing. AI reads every view and dimension, builds a solid 3D model, and checks it back against your drawing. View your 3D model, then download the STEP and STL files and a quality report.
See it work
When you have the drawing but not the model
Legacy parts
Drawn before 3D CAD: paper prints, scans and old 2D files with no model behind them.
Replacement parts
The machine still runs but its maker is gone. Remake the part from its print.
A customer’s print
Customers send a PDF, not their CAD. You still need a model to quote and program.
A lost model
Lost in a migration, or saved in a format nothing opens anymore.

Build your 3D Model
For $9.99 we build the part from your drawing and you look it over in our viewer, with its quality report, before you buy the CAD files.
- 3D Viewer – inspect your model in the browser
- Quality Report – every dimension checked against your drawing
- Share link – show the model to anyone, no login

Compared with a drafting service, freelancer or 3D scan
| Compared on | AI (Drawing to STEP) | CAD drafting service | Freelance marketplace | 3D scan service |
|---|---|---|---|---|
| Turnaround | Minutes | Typically a quote first, then days | Roughly 1–4 days, plus revision rounds | Ship the part, then days |
| Price | $9.99 to build, files from $29.99 | Quoted per drawing | Roughly $10–30+ per gig | Scan fee plus modelling fees |
| Price up front | Yes: Shown after the free check | No: Quote first | Yes: Listed on the gig; revisions may add | No: Quote first |
| What you send | The drawing | The drawing and a brief | The drawing, a brief and answers to questions | The physical part |
| Output | STEP, STL and a quality report | CAD or STEP, depending on the service | Whatever you agree on | A mesh, then CAD after mesh-to-CAD cleanup |
| How it’s checked | Every view compared against your drawing | The drafter’s own review | Your review of the file, then revisions | Against the scanned part, not a drawing |
| Privacy | Never used to train AI; deleted after 90 days | An NDA, if you arrange one | Depends on the freelancer and the platform | Your part leaves your hands for days |
| Best for | Parts and assemblies with a complete drawing, legacy prints included | Ambiguous drawings that need a conversation | Trivial parts at the lowest price | No drawing at all, worn parts, or organic shapes |
Frequently asked questions
Is this a PDF to CAD converter?
Yes, but to 3D: most PDF to CAD converters trace flat 2D DWG lines, while this builds an editable STEP solid any CAD package can open.
How long does a conversion take?
Minutes, not hours or days, from payment to download. It is fully automated, so there is no drafter’s queue.
How much does it cost to convert a drawing to STEP?
$9.99 builds the 3D model you see first. The CAD files are from $29.99 per part, paid once, the $9.99 counted toward them.
How is the 3D model checked against the drawing?
Every view on your drawing is compared with the same view of the model. If the drawing leaves something out, we ask you.
Can it convert old or scanned prints?
Yes, if the views and dimensions are legible: paper prints, scans and photos all work. The free check tells you before you pay.
Which parts can’t it convert yet?
Freeform surfaces, and drawings with missing views or dimensions, such as an assembly drawing that leaves its parts undimensioned. The free check tells you before you pay.
Are my drawings kept private?
Yes. No drafter or freelancer ever sees your drawing; it is never used to train AI, and it is deleted after 90 days, or sooner if you ask.
Should you check the model before manufacturing?
Yes. 3D print the STL and measure the critical dimensions against your drawing before the STEP goes to a machine shop.
