What does DB Up and DB down mean

[sopwath]

I've been messing around with the editor (mostly because I need a break from trying to get Hard6 to work)

I finally figured out how to set waypoints correctly.  I even got the ground colored the way I want it...

Here's a few questions:
What does DB up and DB down do in the Object mode of the editor?

How can I change the water level?  In the level I've got now, I just moved the land down, but theres still some wierd ease of use issues when I want to put a boat in.

How do I make the hydraulics move during the boat phase of testing?

Thanks in advance for the help,

Newbie fits me well.  DB means Draw Bridge.  Duh.  You can set it up with DB up (set to its own phase) and put it down with DB Down (set to a separate phase)  Sorry.

How about that water?

Put the mouse cursor where you want the water level to be and press L.
