Doodad(or destructable) Z at Location?

Is there any function that will allow me to find the Z height of a doodad or destructable at a given point? I know of one way i can do it but it takes lots of time and lots of space that is unnecesery so a trigger function would be a lot easier and better. If there isn't a function like this does anyone have an alternative?

wyrmlord made a tool for changing the *.doo file from a map into trigger form.

Just use the tool to extract and view the doodads in trigger form then copy and past the Z part of each trigger. That’s the fastest way I know.

If you’re trying to find the Z point of a destructible or doodad in game with triggers only you can’t do it. I've already tried.
Although you can make a trigger to place the same doodad at the exact location of the doodad with the same facing angle then use the up/down arrow buttons and get the player to move the doodad until it aligns itself but I don't think you want to do this.
