Using WED and SED for create a App.

I learnt with workshops to load models and terrains.
With that knowledge i placed on terrain models using 3d coordinates and change that coordinates for make motion.
Now i want to make a forest and travel it with a helicopter on 3rd person view and sometimes, some events and locations, have a script for move the camera on several angles and distances.
It seems easier to make the forest with wed but how the lite-c knows the placement of a object selected on wed?

Using WED, skills can be set for objects, and during engine run time, using lite-c, and the c_scan instruction, objects can be "detected" and checked for skill assignments, but that probably doesn't adequately answer any relevant questions in this scope.
