How to View NX .PRT Files on MacBook

As a MacBook user, you may have encountered difficulties when trying to view NX .PRT files. NX is a popular computer-aided design (CAD) software used by engineers and designers to create 3D models. Unfortunately, the native NX .PRT file format is not compatible with macOS, which can be frustrating if you need to view or collaborate on these files. However, there are several solutions available that allow you to view NX .PRT files on your MacBook. In this article, we will explore these options and provide you with valuable insights on how to overcome this challenge.

Understanding NX .PRT Files

Before we delve into the solutions, let’s first understand what NX .PRT files are. NX is a powerful CAD software developed by Siemens PLM Software. It is widely used in various industries, including automotive, aerospace, and manufacturing. The .PRT file extension is used by NX to save 3D part models. These files contain detailed information about the geometry, dimensions, and other properties of the 3D model.

Solution 1: Using Siemens NX Viewer

Siemens PLM Software provides a dedicated viewer for NX files called Siemens NX Viewer. This viewer allows you to open and view NX .PRT files on your MacBook without the need for a full installation of the NX software. Here’s how you can use Siemens NX Viewer:

  1. Visit the Siemens PLM Software website and navigate to the “Downloads” section.
  2. Look for the Siemens NX Viewer and download the appropriate version for macOS.
  3. Once the download is complete, install the viewer on your MacBook.
  4. Launch the Siemens NX Viewer and open the desired .PRT file.
  5. You can now view and navigate the 3D model within the viewer.

Siemens NX Viewer provides a user-friendly interface with various tools for inspecting and analyzing the 3D model. You can rotate, zoom, and pan the model to examine it from different angles. Additionally, the viewer allows you to measure distances, angles, and other dimensions within the model.

Solution 2: Using Third-Party CAD Viewers

If you prefer not to use the Siemens NX Viewer, there are several third-party CAD viewers available that support the NX .PRT file format. These viewers offer similar functionality to the Siemens NX Viewer and can be a viable alternative. Here are some popular third-party CAD viewers for macOS:

  • Autodesk Fusion 360: Fusion 360 is a comprehensive CAD software that also includes a viewer. It supports various file formats, including NX .PRT files. You can download Fusion 360 from the Autodesk website and use it to view and collaborate on NX files.
  • eDrawings: eDrawings is a lightweight CAD viewer developed by Dassault Systèmes. It supports a wide range of file formats, including NX .PRT files. You can download eDrawings from the official website and use it to view and share NX files.
  • Onshape: Onshape is a cloud-based CAD software that offers a built-in viewer. It supports NX .PRT files and allows you to view and collaborate on them directly in your web browser. Simply sign up for an Onshape account and upload your NX files to get started.

These third-party CAD viewers provide additional features and capabilities beyond just viewing the NX .PRT files. They often include tools for annotation, markup, and even basic editing of the 3D models. Depending on your specific requirements, one of these viewers may be a better fit for your needs.

Solution 3: Converting NX .PRT Files to a Compatible Format

If you frequently receive NX .PRT files and need to view them on your MacBook, you may consider converting them to a compatible format. By converting the files, you can open them using native macOS applications or other widely supported CAD software. Here are two common methods for converting NX .PRT files:

  1. Export to STEP or IGES: NX allows you to export your .PRT files to the STEP (.stp) or IGES (.igs) file formats, which are widely supported by various CAD software. To export a .PRT file, open it in NX, go to the “File” menu, select “Export,” and choose either the STEP or IGES format. Once exported, you can open the converted file using applications like Autodesk Fusion 360 or other CAD software that supports these formats.
  2. Online File Conversion Services: There are several online file conversion services available that can convert NX .PRT files to a compatible format. Simply upload your .PRT file to one of these services, select the desired output format, and wait for the conversion to complete. Once converted, you can download the file and open it on your MacBook using native macOS applications or other CAD software.

Converting NX .PRT files to a compatible format provides flexibility and allows you to work with the files using a wide range of software options. However, it’s important to note that the conversion process may result in some loss of data or fidelity, especially for complex 3D models. Therefore, it’s recommended to keep a backup of the original .PRT files in case you need to access the full capabilities of NX in the future.


Viewing NX .PRT files on a MacBook may initially seem challenging due to the lack of native compatibility. However, with the solutions mentioned in this article, you can easily overcome this limitation and view NX files on your MacBook. Whether you choose to use the Siemens NX Viewer, third-party CAD viewers, or convert the files to a compatible format, you now have the tools and knowledge to access and collaborate on NX .PRT files seamlessly.


Q1: Can I edit NX .PRT files on a MacBook?

A1: Editing NX .PRT files on a MacBook requires the full installation of the NX software, which is currently only available for Windows. However, you can convert the .PRT files to a compatible format and edit them using other CAD software that supports macOS.

Q2: Are there any free CAD viewers for macOS?

A2: Yes, there are free CAD viewers available for macOS, such as eDrawings and Onshape. These viewers offer basic viewing and collaboration features for NX .PRT files without the need for a paid license.

Q3: Can I view NX .PRT files on my iPhone or iPad?

A3: While there are no native NX
