What is PRT file?

A .PRT file is a proprietary file, also known as the 3D & CAD file, is created by the Pro/ENGINEER CAD software. The PRT file comprises a part of the component or the manufacturing part design in 3D model. Further, by combining multiple PRT files into an assembly file, a complete and final 3D scene can be created. The assembly files are stored with an extension asm or assem.

Programs which support PRT file extension

The following listing features PRT-compatible programs. Files with PRT extension, just like any other file formats, can be found on any operating system. The files in question may be transferred to other devices, be it mobile or stationary, yet not all systems may be capable of properly handling such files.

The operating systems may note enough free resources to run the application that support PRT files. Close all running programs and try opening the PRT file.

5. Ensure that you have the latest drivers and system updates and patches installed
