This is a superb quality mesh of the engineering section of a Galaxy class ship like the Enterprise-D. It includes turbolift entrances, to the central console, to Geordi's office right through to the warp core. To see a walkthrough animation download this movie. The mesh as it is reports three missing maps and some missing UVW Coordinates, but it renders just fine as you can see in the thumbnail. I'm still trying to find the missing maps.
