I'm trying to use some KML 3D models that are not responding to Explorer 3D vertical exaggeration settings. If exaggeration is low, equivalent to "1" in Google Earth, things are fine. If I dial up the exaggeration in Explorer, the exaggerated basemap terrain covers up the KML, which remains unchanged. The KML was produced by exporting surface models from AutoCAD Civil 3D.
Anybody else have a similar problem?
