Instructions
Locate the file "base.SC2assets" in the "StarCraft 2" directory under "Program Files(x86)/Starcraft 2/mods/Liberty.SC2mod."
Right-click the "base.SC2assets" file and select "open with..." to find the MPQ editor. Select "Browse" to search your computer for the program, as it will not be on the list the first time you use it.
Find the file "BattleCruiser.m3" in the "base.SC2Assets/Assets/Units/Terran/Battlecruiser" directory, in the list of files in the right column. Right-click the file and select "Extract." Note where the program sends the file.
Open the "base.SC2Assets/Assets/textures" folder in the MPQ editor and find the "battlecruiser.dds" texture file. Extract this file the same way you extracted the ".m3" file.
Open the files you extracted with your chosen 3D modeling program to see the structure and textures of the Battlecruiser unit.
