Help with getting data / shapes from Rhino into Mapbox / GIS software?

Hello all,

I’ve been an avid Rhino user for about 6 years and have never come across this problem before:

I’m looking to export a full-scale shape as either a CSV or GeoJSON file (even if some conversion is needed) from Rhino 5 into software like Mapbox or QGIS.

Essentially, I have this shape defined as a radius at 100% scale and can export as ‘object properties (.csv)’, but the mapping software constantly refuses the file as it does not have any latitude / longitude properties. Is there a way to even attribute lat/long to a polyline in Rhino via the cPlane or…?

I appreciate all the help you guys can give me on this topic.
