UVW Box mapping adding

Simple macroscipt for adding simple UVW box mapping with 100x100x100 units.
Very useful for archiviz.
Tested in 2017 version, but as it is simple macro code I am pretty shore it will work on every 3dsmax version.
Run the script, open Customize menu, go to Keyboard tab and assign some letter of number, and that is it!
Cheers!

Thanks!

BTW, there is similar script, commercial, with interface, but with just one button click, this the way more faster!
...and most important, do not forget TO SELECT object before starting the macro!
