I don't know. And there might be more than one, because some parts are done by subcontractors.
if you open the STEP files with a text editor, you should be able to know the last STEP producer/exporter.
the header is something like this:

Code: Select all

ISO-10303-21;
HEADER;
FILE_DESCRIPTION (( 'STEP AP214' ), '1' );
FILE_NAME ('sphere.STEP','2016-09-25T16:33:48',( '' ),( '' ),'SwSTEP 2.0','SolidWorks 2014','' );
FILE_SCHEMA (( 'AUTOMOTIVE_DESIGN' ));
ENDSEC;
DATA;
In FC you get something like the following:

Code: Select all

ISO-10303-21;
HEADER;
FILE_DESCRIPTION(('FreeCAD Model'),'2;1');
FILE_NAME('example.step','2020-01-13T07:43:58',(
    ''),(''),'Open CASCADE STEP processor 7.3',
  'FreeCAD','Unknown');
FILE_SCHEMA(('AUTOMOTIVE_DESIGN { 1 0 10303 214 1 1 1 1 }'));
ENDSEC;
DATA;

This model from MAORY has been chosen by Phoronix to illustrate the release of version 0.19 of FreeCAD:

https://www.phoronix.com/scan.php?page= ... eeCAD-0.19

That was an old model, we have updated it, and the new one is quite different, you can find more info on ESO's site and the consortium's site. We have recently released the PDR documents (Preliminary Design Review) and I have used FreeCAD to make the illustrations, and I'm happy to say that FreeCAD's assembly is both powerful and easy to use.

IMPRESSIVE WORK! How long does it take to pickup the freecad API to create a custom workbench plugin? I am interested in creating a plugin for composites design.

Well i decided to dive into the API. Far so good i have some rudimentary surface peeling working in the python console. Eventually this will become a composite layup pattern and stress analysis tool.

Just out of curiosity: how much physical RAM (RES MEM on Linux) does this 120MB model consume?
