Dont use the editor for these. They are Zeus only compositions. The 3den is used for creating compositions to then paste into live games as follows

Step 1: Create mission in 3den/Editor with a zeus module setup (Make sure none of the models you want are set to "Simple Object" and also make sure it is built in the place you want as you cant move its possition)
Step 2: Play mission as zeus go to center of mission area
Step 3: Util-Add Object to Zeus (Set radius to include all item you want saved)
Step 4: Make sure your zeus module isnt visible to you in zeus (If it is move it far away)
Step 5: Save/Load - Create mission SQF (Place in the same place with the same radius as step 3)
Step 6: Copy the text that appears and save to a .txt on your desktop with a name you can remember
Step 7: Enter server running zeus + ares
Step 8: Util-Execute Code (Server) (Paste the code in here and wait for it to load)
Step 9: Go to the area it was created the check it loading in correctly. (Sometimes you have to wait 5minutes for object to rotated themselves if it is a large .sqf)
Step 10: Send in the troops
