One possibility would be to use http://www.openscad.org/ as some sort of intermediate language.

edit: And there are apparently a few standardized, lower-level ASCII formats including https://en.wikipedia.org/wiki/AutoCAD_DXF and https://en.wikipedia.org/wiki/STL_(file_format).

Of course OP probably still has their work cut out for them as far as building something useful on top of these goes.

thanks for that useful input. That is exactly what my question is. If there is clarity around these aspects, what the founder would become undoubtedly awesome.
