The STEP computer-aided design file type was released in 1994 after a decade of development
to make it easier to share geometric models. STEP, or STP, is short for Standard for the Exchange
of Product Data and is the ISO 10303-21 standard for representing 3D objects.
The real strength of STEP is its interoperability, which allows designs
to be viewed and modified by different CAD programs.
