Generally speaking, .prt files used to store 3D models of components or mechanical parts as well as to exchange these models between CAD applications. If you need to export the data to DWG format, you have to use a program that allows this kind of data translation.
Most of the modern CAD programs should be able to perform prt to dwg conversion, that is at least of the most common .prt files from industry standards (Creo, Solid Edge etc.).Open PRT file Open DWG file
