How to view .WMO 3D models from Cataclysm client?

[WithinAmnesia 17]

How does one view or even export .WMO 3D models from the Cataclysm (and perhaps the 3.3.5.) client?

I want to make a new dungeon from splicing together World of Warcraft .WMO models.

I am not good at making digital tools (or getting them to run); I focus on my strengths of world creation, game design, Itemization, plot and story writing, concept art and 2D and 3D game art.
