About P21 files

P21 is a type of CAD file used by the Product Data Exchange (PDX) standard, developed by the Automotive Industry Action Group (AIAG). It is a text-based file format used to store product data and engineering information. P21 files are generally used to store product models and other related data, such as parts lists, assembly instructions, and engineering drawings. They can also be used to exchange product data between different CAD systems.

The P21 file format is supported by a variety of CAD software, such as Autodesk Inventor, SolidWorks, and CATIA. However, it is not supported by all CAD software, so it may be necessary to convert P21 files to a different format in order to use them in other programs. Some of the most common file formats that P21 files can be converted to include STEP (.stp), IGES (.igs), and STL (.stl).

When converting P21 files, it is important to consider the accuracy of the conversion. Some CAD programs may not support all of the features of the P21 format, so the converted file may not be an exact representation of the original. Additionally, the complexity of the model can make it difficult to accurately convert the file. It is also important to consider the compatibility of the converted file with the software that will be used to view or edit it.

Due to the complexity of the P21 file format and the potential for inaccurate conversions, it is often preferable to use an online service such as Convert.Guru to convert P21 files. Convert.Guru provides a free and easy way to convert P21 files to a variety of popular formats, including STEP, IGES, and STL. Additionally, Convert.Guru can be used to convert P21 files to other CAD software formats, such as Autodesk Inventor, SolidWorks, and CATIA.


The P21 Converter Story

The history of Convert.Guru began more than 25 years ago in California, when Tom Simondi published the most comprehensive database of file formats on his website. Before that, Tom had worked on Space Shuttle development at the Air Force Systems Command’s Space Division in Los Angeles. He is known as one of the top programmers of the late 1980s.

When Microsoft integrated Tom’s Filext database into Windows XP, it became the leading platform for analyzing and processing file types and formats.

Today, we use the latest technologies to analyze, process, and convert one of the world's largest collections of file formats. We are committed to developing the best P21 converter by continuously improving quality, usability, and reliability.
