Drafting Room 5

From Memory Alpha, the free Star Trek reference

Drafting Room 5 is one of several large drafting rooms for starship design, testing and construction in Mars Station at the Utopia Planitia Fleet Yards.

Much of the Galaxy-class Starship Development Project, including the majority of ship construction, design work and system model tests, was based out of Drafting Room 5. (TNG: "Eye of the Beholder")

Drafting Room 5, along with Dr. Leah Brahms, was recreated on the holodeck of the USS Enterprise-D in 2366. It served as a productive environment in which to devise a means of escaping the Aceton assimilators. (TNG: "Booby Trap") A year later, Doctor Leah Brahms ran the program on the holodeck of the USS Enterprise-D again. (TNG: "Galaxy's Child")
