I have created a new CDB area with elevation data, imagery, areals, linears and a single point feature in the terrain in TV 6.0. The resulting CDB looks fine on disk and the TV browser.

Thea Lite only renders the terrain polygons with the imagery.

Does the Thea Lite rtp support the other parts of CDB ?

Currently Thea only supports these CDB layers:
1.  Terrain
2.  Geospecific Culture Man-made
3.  Geotypical Culture Trees
4.  Polygonal Insets

What is a polygonal inset in CDB specification terms?

A Polygonal Inset is a point feature in the GSFeature dataset in the man-made selector whose bounding sphere is larger than 1 kilometer in radius.

Thanks for the clarification.

So a 1 km bounding radius is an arbitrary heuristic that Thea Lite uses to process “site models” as reference by this post since this heuristic and usage is not described in the CDB 3.0 specification?  What does Thea Lite do specially for such features?

Actually it is an artifact of how the VegaPrime CDB support was implemented that Thea is built on top of.
