Save environment values to file

after i create an environment by unity, such as a unit, i want to create a txt file for recording all the walls and objects in the unit, with their location, x, and y position, their hight.

what kind of software so you suggest? and is there any manual for the process?

thank you.

This might be what you're looking for: Save and Load from XML

Of course, you'll have to scan through it and alter it for each object in one text file.
