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.
