I can't help you directly (as I don't have the deluxe version with theSDK) but I think this link will help:
Abacus-Scenery Shortcut.
It is the instruction and download page for Scenery Shortcut, free from Abacus, a small utility that allows simple conversion of mission scenery created with the Mission Builder/Object Placement Tool, to standard scenery.
It instructs on how to get the Object Placement Tool working, how to use it, and how to convert the scenery using the Scenery Shortcut tool.

At that time [1909] the chief engineer was almost always the chief test pilot as well. That had the fortunate result of eliminating poor engineering early in aviation.
