You want to use the assign_vertices_3d() function that I posted to the 
list recently. Use the Level as the z-value of the coordinates. You mig 
need to scale up the values if you are working in meters rather than 
degrees.

There is some basic support for "turn restrictions" which is what you 
are looking for. But it is not well documented or very easy to use and I 
believe it only works with shooting start analysis.
