As noted, if you want the "classic series" bridge, Ptrope got permission to adapt SeanR's LightWave model into a collection of Poser coded prop (.PP2) files.

It includes the secondary exit and the ceiling mounted intruder defense array introduced in the 1973 Filmation produced animated series.

Ptrope also offers a transporter room, crew quarters (both single and shared units) as well as the briefing room which he modeled from scratch. He's even made the iconic "Burke" styled tulip chairs. One of the two versions has a hole in the back so Lt. M'Ress won't have to sit upon her tail! So be sure to examine the rest of his listings.

For the engine room, ALT1701 has a .OBJ model at SharCG and for the curved corridor section XCalPro.com has a Poser prop file.

Sincerely,

Bill
