Description

The STP file format, which can also be found with the extension STEP, is a 3D format defined in 1994 and used to store 3D objects for use in computer-aided design (CAD) applications. STP files are text-based, formatted files containing one instance per line.

Although STP files are widely supported by most CAD applications, the format does have its limitations, such as the necessity to read the complete file into memory in order to parse the contents, and due to the textual storage of information, the files can be quite large.
