No, actually you can load more vector layers over a raster map using nviz

for example you can type

/nviz elevation=dem vect=streets,streams
/
and you will be loading two vector layers (streets and streams) over a 
raster dem map.

If you have nviz already loaded you have to go to Visualize/Lines 3D 
Polygons or Points and use "New" button. To switch the layer 
configuration just pick the button with name of the layer in front of 
"Current".
