2d map animated directory: using path

help sir we are trying to make a 3d map of some place here in the philippines
and we would like to ask if you could help us:

the logic:

a list of spots or building are listed in a menu
and whenever an individual choose a building
a red line will appear and show the way

FROM the point of reference to the destination

Looks like a job for the Game Engine. If you do not mean that, let me know.
