- See List of STEP (ISO 10303) parts:
- Part 21 - STEP-File Clear text encoding of the exchange structure
- Part 214 - Core data for automotive mechanical design processes
- One is an implementation method (defines the physical file format), and the other is an Application Protocol ... what's not to understand? —Dennette 03:46, 26 December 2006 (UTC)
This entry is largely devoid of useful information for those interested in a comparison between capabilities of different exchange formats for surfaces and solids. For anyone interested in assisting, see the wikipedia page for IGES format which mentions the capabilities and that STEP format supposedly is to replace IGES. However IGES is not even mentioned in this entry.
ISO 10303-21 is not directly related to IGES. Only when it is used to exchange application data along the data models defined in STEP APs 203 or 214 we can establish a relation. AP203/214 are successors of IGES. -- Lothartklein (talk) 17:46, 26 November 2008 (UTC)

List of Programs?
It's not very helpful to know that in such and such year some standard allowed longer file names or whatever but not whether there are any existing free or commercial programs that can open files written in the damn standard, is it? — Preceding unsigned comment added by 18.104.22.168 (talk) 18:04, 23 June 2014 (UTC)
