Hi,
You can use that way:
"Options>Element Attributes>Attribute Manager>" >>> Surface Tab
Then you will see "Current File: Untitled.aat" box at right side. Now select your prefered surface (or all of them) at left side and "Append>>" to right side.
Then Save this "*.aat" file and now you can use this *.aat file anytime.
How to use my "*.aat" files?
Again: "Options>Element Attributes>Attribute Manager>" >>> Surface Tab
Use Open button at bottom of right side box and open your "*.aat" file. Thats it!
peace...
