How to Display an NX CAD Model in Adobe Acrobat 2017
Question details
The user wants to know how to embed and view a 3D model from NX CAD software within a PDF document using Adobe Acrobat 2017.
- Product
- Adobe Acrobat 2017
- Device & OS
- not provided
- Scenario
- Attempting to embed or view interactive 3D models originating from NX CAD in a standard PDF file.
- Observed behavior
- Native NX CAD models cannot be viewed directly in Acrobat; they require conversion to supported 3D PDF formats like U3D or PRC before they can be displayed.
Ensure you have access to Siemens NX or a compatible 3D conversion tool to export your CAD model, and verify your Adobe Acrobat 2017 is updated to the latest version.
Convert NX CAD to Supported Formats and Enable 3D Content
Convert your NX CAD model into a U3D or PRC file, embed it into your PDF, and adjust Acrobat settings to allow 3D rendering.
Adobe Acrobat 2017 does not natively support direct imports of native NX CAD files. To interact with 3D models within a PDF, the CAD data must first be published or converted into recognized 3D formats, specifically Universal 3D (U3D) or Product Representation Compact (PRC).
Open your model in Siemens NX or your preferred 3D CAD conversion software, and export the file as either a U3D or PRC format.
Launch Adobe Acrobat 2017, navigate to 'Tools' > 'Rich Media', and click the 'Add 3D' tool. Drag a rectangle on the page where you want the model to appear, and select your converted U3D or PRC file.
Go to 'Edit' > 'Preferences' (or 'Acrobat' > 'Preferences' on Mac). Select the '3D & Multimedia' category on the left, and check the box for 'Enable playing of 3D content'.
When you open the PDF, look for a yellow security warning bar at the top. Click 'Options' and choose 'Trust this document one time only' or 'Always trust this document' to render the interactive model.

While highly specialized 3D CAD embedding requires specific Adobe Acrobat workflows, WPS Office offers a lightning-fast, highly compatible alternative for all your standard PDF reading, editing, and conversion tasks.
Frequently Asked Questions
What formats are supported for 3D PDFs in Acrobat 2017?
Adobe Acrobat 2017 natively supports Universal 3D (U3D) and Product Representation Compact (PRC) formats for embedding and displaying interactive 3D models.
Why is my 3D PDF showing a blank space or a security warning in Acrobat?
By default, Acrobat disables 3D content to protect against potential security vulnerabilities. You can fix this by clicking 'Options' on the yellow message bar and selecting 'Trust this document', or by enabling 3D content permanently in Edit > Preferences > 3D & Multimedia.
Can I directly open an NX part (.prt) file in Adobe Acrobat?
No, Adobe Acrobat cannot directly open or render native NX CAD (.prt) files. The files must be translated into U3D or PRC formats using CAD software or a third-party conversion tool first.
