Convert STP to PDF

Verified by Adam B.· reviewed by FE Editorial ·updated Aug 27, 2026
QUICK ANSWER
Is it possible to convert STP to PDF?
Yes - STP converts to PDF.

Open the .stp file in a CAD application and use its drawing or print function to export a PDF. Most people want a flat 2D view of the part; interactive 3D PDFs that readers can rotate require specific tools and a 3D-capable PDF viewer.

Why convert STP to PDF?

A PDF is easy to share without CAD software. Engineers export .stp models to PDF to send a part view to colleagues, attach to a quote, or include in documentation. .pdf freezes a specific view for communication, while the original .stp (ISO 10303) preserves full parametric geometry.

How to convert STP to PDF

SolidWorks APP

Open the .stp file, create a drawing document with projected views, then use File > Save As and choose PDF to export a dimensioned engineering drawing.

Autodesk Inventor APP

Import the .stp model, switch to the Drawing workspace, add projected views, then export as PDF from the Output menu.

TurboCAD APP

Open the .stp file and use File > Print or File > Export to save the drawing as a PDF.

About these formats

.STP STEP - Standard for the Exchange of Product Data (ISO 10303), .stp spelling

An STP file is a 3D CAD model - a part or assembly - stored in the ISO 10303 STEP format so it can move between different CAD programs. The fastest free options are FreeCAD, CAD Assistant,…

.PDF Portable Document Format

A PDF (Portable Document Format) is a fixed-layout document that looks identical on every device - fonts, images, and layout are all embedded. Open it in any browser or the built-in viewer…

Quality & what to watch

  • The PDF captures a visual snapshot of the 3D model; all parametric CAD data (feature tree, tolerances, dimensions) is not preserved in the output.
  • Interactive 3D PDFs - where readers can rotate the model - require specialized tools to create and a 3D-capable PDF viewer to open.
  • For a quick result without installing software, open the .stp in a viewer and use its print-to-PDF function.

Frequently asked questions

Can I get a dimensioned drawing PDF from an STP file?
Yes - use SolidWorks or Autodesk Inventor to create a drawing with projected views and dimension annotations before exporting PDF.
What is the difference between a 2D PDF and a 3D PDF of a STEP file?
A 2D PDF shows a fixed view of the part; a 3D PDF embeds the model so readers can orbit it, but requires specialized software to create and a 3D-capable viewer to open.
Can I convert STP to PDF without installing software?
Yes - use an online CAD converter, or open it in a viewer and use its print-to-PDF function for a quick visual result.
