Adding objects.

Luckily the SDK has plenty of pre-made models for you to place in your levels, from rocks and tree's to functioning helicopters and buildings. Go into the "object" window on the Roll-bar. click on "Geom Entity", then you can hit objects and choose your model or type something you may want in the search box at the bottom of the window.

once you have found an object you like click on "Follow Terrain" (means the object follows the terrain) on the top tool bar then drag and drop your object onto your level.

now once your object is in the scene you will notice your x,y,z axis are on it. This is so you can adjust your object the way you see fit. when you click on the object you can select a tool to use to manipulate it using your number keys.

1. pressing one enables you to adjust its position
2. pressing 2 enables you to adjust its rotation.
3. pressing three enables you to adjust its scale.

Or alternately you can select one of the tools using your mouse from the top tool bar.

Another cool Hotkey is to hold down "Shift,Ctrl,Alt" and then left click anywhere on the Terrain and the object will be moved there. Keep adding models till you are happy.
