What is a .P21 file?
The file extension .P21 refers to a type of file known as an Express STEP Data Model File. This file format is used to store 3D models that represent and exchange product data in three dimensions. The content of a .P21 file is saved in ASCII text format, which is a simple text format that can be read by humans and computers. The structure and rules for this file format are defined by the ISO 10303-21 standard.
.P21 files are primarily used in industries related to automation systems and for integrating various industrial processes. This makes them important in sectors where precise 3D modeling of products is necessary for manufacturing and other automation applications.
To open a .P21 file, you can use a program called LKSoft JSDAI for Eclipse. This software supports Express AIM (Application Integrated Model) and MIM (Modular Integrated Model) files. However, it's important to note that while .P21 files are used for specific purposes, similar files with the .STP extension are also used and require compatible software to open and manage them.
