KMZ Exporting just one point?

Hello

I created a google map a few years ago and managed somehow to export an outline to overlay (was using Rhino 5 at the time). I need to do this again but cannot figure out how I did it before? I have set my earth anchor point, perspective view angle and exported to KMZ but Google Maps just imports one point which funnily enough is where I set the earth anchor point.

I’ve also imported the KMZ file in QGIS and it shows the same point with nothing else. I can export the existing lines from my Google Map into QGIS no problems.

Can anyone tell me what I’m missing? Version 7 SR12
