What's all needed to make a zone?

[JrFaust]

I used DungeonBuilder 1.9. I made my dungeon no objects in it just the dungeon exported it to a .sd3 file. I wanted to see if I could use OZ to place some objects into it but it just crashes when I try. (That maybe the problem)

I placed the .sd3 file in my client directory. Then added it to my zone table in my database gave it an ID of 750 since that wasn't used and safecoords of 0, 0, 0 and the rest of the setting were default. Now when I use #zone to zone over it gives no errors but I don't zone. What part(s) have I messed up?

Thanks for your time.
