PRT File - opening and understanding

Did your computer fail to open a PRT file? We explain what they are used for and recommend software that we know can open or otherwise handle your .PRT files.

What is a PRT file?

The .prt file extension is most commonly associated with the Pro/ENGINEER CAD software application. Files with the .prt extension contain part files that are created with the program. These files are used in the design of manufactured parts and contain part information including the structure of the part and a 3D model. Multiple PRT files can be combined into an assembly file, which is given the .asm file extension.

The .prt file extension is also used for Dr.Halo printer driver files, P-CAD component files, IRMA Workstation for Windows printer configuration files, WordPerfect Presentations document template files and Microsoft Schedule+ print files.
