A friend of mine had this wonderful program and was able to export not only texture maps from created planets but also when "landed on an object" was able to export an actual geometry of the surface.
No, you can't export planet surface geometry, and it has never been possible to do so. You can export a planetary height map, but it would be relatively low resolution and not useful for local-scale details. The capability to export a local height map may be implemented eventually, but it won't happen anytime soon.
