Export STEP with metadata

Rhino

Hi! Is the Rhino .stp exporter able to include metadata per object? If not, would this be too hard of a feature to include? Ideally, it would be great if the Rhino Object userstrings becomes metadata in the .stp
@dale?

@tim - is this something you know about?

Hi David,

This might be possible. Do you have a really, really simple (like a single plane) step file with metadata on an object that I could look at? That would help in trying to figure out what step entity I need to look at. I realize you’re asking for export but knowing what to actually set is what I’m trying to accomplish from a file already written.

I need this as well.. Is it possible to specify meta data for a STEP file in Rhino?

Hej Morten -

Did you see Tim’s request about an example? Without such thing, nothing will be done…

I asked Copilot to create a sample file but it was nonsense…

So here’s a simple *.stp file I exported out of Artec Studio.

The header:

ISO-10303-21;
HEADER;
FILE_DESCRIPTION(('STEP AP242'),
    '1');
FILE_NAME('Cylinder 1',
    '2025-03-19T16:17:40',
    ('Default author'),
    ('Default organization'),
    'Artec Studio 19 Professional x64 19.2.2.54 (ge1d21f7574)',
    'C3D Toolkit',
    'Default authization');
FILE_SCHEMA(('AP242_MANAGED_MODEL_BASED_3D_ENGINEERING_MIM_LF { 1 0 10303 442 1 1 4 }'));
ENDSEC;

Cylinder 1.STEP (3.8 KB)

Let’s say I’d want to get the author name… I can get that through Grasshopper with the read file component…

Maybe @dadandroid could also add a file and his ideas about metadata?
