Convert 3D PDF to STEP – checked, ready for your CAD
You have a PDF in which the part can be rotated and zoomed? Then it already contains a 3D model (usually in PRC or U3D format). We extract it, check it and deliver a clean STEP file that you can keep working on in SolidWorks, Inventor, Fusion 360, Creo, CATIA, NX, FreeCAD or any other CAD system.
How it works – in 3 steps
- 1
Upload your 3D PDF
Use the order form, choose “3D PDF → STEP” and upload the file (up to 25 MB). No account needed.
- 2
We extract and check the model
We pull the embedded model out of the PDF, check surfaces, units and completeness, and note anything unusual in a short report.
- 3
Receive your STEP file
Within 1–3 working days (express 24 h) you get the .step/.stp file, a preview image and the report by email.
How do I recognise a 3D PDF?
Open the file in Adobe Acrobat Reader. If you can rotate the part with the mouse, it is a 3D PDF. If you only see flat views with dimensions, it is a 2D drawing – we can build a STEP model from that too, see “2D drawing to 3D model”.
PRC or U3D – why it matters
3D PDFs store the model in one of two formats. PRC can contain exact CAD geometry (real surfaces), which converts into a proper solid STEP model. U3D only contains a triangle mesh: it looks the same on screen, but a STEP file made from it is not a real solid and is hard to edit. We check which one your file contains before we start – if it is U3D, we tell you and offer to rebuild the part as a real solid from the views (“2D drawing to 3D model”).
Where 3D PDFs usually come from
Supplier and manufacturer catalogues, quotes and data sheets often include 3D PDFs so you can view a part without CAD software. As soon as you want to design around that part – a bracket, a housing, an assembly – you need the model as STEP. That is exactly what we deliver.
What you receive
A STEP file (.step or .stp, AP214 or AP242), a preview image and a short inspection report. On request we also deliver IGES or STL. Assemblies are delivered as STEP assemblies with their individual parts.

FAQ
Isn't that the same as a free converter?
Free converters often only output a mesh or fail on large files, and you only notice once the file is in your CAD. We check the result and deliver a STEP file that opens cleanly – see the comparison above.
Can I extract the model myself?
Yes, if you have the right tools: some CAD systems and paid plug-ins for Adobe Acrobat Pro can export the embedded model. If you don't have them or the export fails, we do it for a fixed CHF 19.
Does it work with assemblies?
Yes. Assemblies from a 3D PDF are delivered as a STEP assembly; we confirm the price after review.
Which STEP version do I get?
By default AP214, which every common CAD system reads. AP242 on request.
My PDF is password-protected – is that a problem?
Only if you are entitled to use it and give us the password. Please confirm in your order that you may use the model.
What if my PDF is not a 3D PDF after all?
Then it is a 2D drawing. We will let you know and can build the 3D model from the views instead (from CHF 39) – only after you agree.
