Can AutoCAD Open PRT Files?

Can AutoCAD Open PRT Files?


If you are working with CAD (Computer-Aided Design) software, you might come across various file formats. One such format is the PRT file format. In this article, we will explore whether AutoCAD, one of the most popular CAD software in the industry, can open PRT files.

Understanding PRT Files

PRT files are native to Creo Parametric, a powerful 3D modeling software developed by PTC. These files contain solid models and their associated data, including geometric information, metadata, and assembly structure. Creo Parametric is widely used in industries such as automotive, aerospace, and manufacturing.

AutoCAD’s Compatibility

AutoCAD does not have native support for opening PRT files.

If you try to open a PRT file directly in AutoCAD, you may encounter an error or find that the file cannot be recognized. This is because AutoCAD uses its own proprietary DWG (Drawing) file format as its default.

Alternative Solutions:

  • Convert PRT to DWG: To work with a PRT file in AutoCAD, you can convert it to the DWG format using specialized conversion software or online conversion tools. Once converted, you can easily open the DWG file in AutoCAD and make any necessary modifications.
  • Importing Options: Depending on your version of AutoCAD and the options available within it, you may be able to import parts or assemblies from other CAD software that support the PRT format. However, this method may not always provide full functionality or preserve all aspects of the original PRT file.


In summary, AutoCAD does not have native support for opening PRT files. However, there are alternative solutions available, such as converting the PRT file to DWG or exploring import options within AutoCAD. It is important to assess your specific requirements and choose the best approach accordingly.

Remember, understanding the compatibility of different file formats is essential in the CAD industry to ensure smooth collaboration and interoperability across various software platforms.
