does anybody know if it is possible to have a 3D vector with faces entities linked to a DB table?
I have data about an urban area. Buildings are composed by walls and roofs faces, I'd like to import the data in GRASS preserving the geometry and the "building element" as much as possible and to link the resulting vector to a DB table.
nviz has some capabilities to allow the mouse selection of vector entities and the visualization of the associated DB records. Is it possible for any 3D geometry entities, including faces, or only for vector points?

give faces of the same building a common category number.
maybe v.extract to select only buildings you want.
I think Markus has already done this? See screenshots of 3D Trento:
