Hi,
I need to export the output file as geojson to load the file over the top of the map. But I don't know geojson file is supported by sketchup
This page shows the import and export file formats for the Pro edition.
( The Make edition was limited to .skp, .dem , .ddf, .dae and .kmz.)
GeoJSON is not a native export format.
However JSON is a plain text format, so is relatively easy using Ruby code.
Checking extensions …
Looks like CityEditor extension does this. But it is not free.

Anyone else know of any other GeoJSON capable extensions ?
