Questions & Answers
PRT files: Frequently Asked Questions
What are PRT files?
The PRT extension is shared by several different file formats, and the type of a file depends on the program that created it. The most common are the part files of CAD systems, in which one component of a product is stored as a 2D drawing or a 3D model. A second kind is a print file, and a third is a raster image in CMYK colors.
PRT (Siemens NX). This is the native file of Siemens NX, formerly Unigraphics, a CAD system for mechanical engineering. It is a proprietary binary file that stores the exact solid geometry of a part, based on the Parasolid modeling kernel, together with the history of its features, parameters, and manufacturing notes. Parts and assemblies share the same extension, and an assembly file only refers to the part files that belong to it, so all of them must stay together. Such files are usually exchanged through neutral formats such as STEP, Parasolid, or JT.
PRT (CADKEY). CADKEY is a 2D and 3D CAD program that has existed since 1984, and its part files can hold wireframe, surface, and solid geometry with dimensions and annotations. Assemblies were stored in .asm files. Since 2004, the program has been continued as KeyCreator, which uses the .ckd extension but still reads old CADKEY parts.
PRT (MegaCAD) and PRT (ProCAD) are part files of two other CAD programs, MegaCAD 2D/3D from Megatech Software and ProCAD, each in its own format.
PRT (Printer Command Language). This is a print file with PCL commands for HP printers and compatible devices, which describe text, images, fonts, and the page layout. PRT (Raster CMYK) is a raster picture in which every pixel is described by cyan, magenta, yellow, and black values, as in print preparation.
