Curves from Rhino to KMZ


I am trying to find a way to import a site boundary from Rhino to Google Earth as curves. I have seen that you could geolocate the curves in Rhino using EarthAnchorPoint and then export a KMZ file. Although when I tried that I could not see the curves in Google Earth, so I guess there is a problem with the geometry format.

Does anyone know a better way to do that?

Thank you!
