The upper decks of the engineering section or secondary hull of the Constitution II class.
About this creation
The complete file. I worked very hard to get the plasma conduits for the engines to rise at the exact angle and position so that I wouldn't have to fix them later on.
Deck N starts with Upper Main Engineering, a cramped room around the vertical intermix shaft. Behind the circuit bay is a pocket for the vertical emergency door on the deck below. Behind that is a chamber filled with subsystems: batteries, hydrogen tanks, a shield generator, and the main thrusters, as well as frame elements for the neck.
Deck O is the Main Engineering deck. Port side is the dilithium control room, a storage room with safety gear, and a bathroom. The main plasma conduit goes aft to the warp nacelles, with a raised platform on one side and a turboshaft on the other. In the equipment bays on each side are more water tanks and batteries. Towards the end is a Jeffries tube leading past the aft phasers to the Flight Control room.
Deck P is the engineering sub-level, with offices and a briefing room. The forward compartments are engineering support areas, including hydrogen tanks and the upper reaction control thrusters around the navigational deflector. Around the plasma conduit is thruster control. Mid-deck are four engineering workshops (Diagnostics, Damage Control, Maintenance, and Power Distribution), followed by a mess hall, various lounges, hangar operations control, and the landing deck hi-bay. Observation galleries line the landing area, followed by enclosed bays for atmospheric gas tanks and pumps to replenish any loss of atmosphere.
Deck Q begins with a life support room, followed by Phaser Control around the intermix shaft. This is flanked by water tanks and shield generators. Behind the battery room is a bank of cargo slots. A catwalk surrounds the cargo hi-bay with access to lounges, docking ports, and damage control rooms. Aft is the Flight Deck.

The Dilithium Control Room, added for Star Trek II, is contained behind a transparent radiation barrier. A revolving door allows crew to access the room without contaminating the entire compartment.
Inside is a cramped, angular set cobbled together from the remains of the Klingon Bridge in TMP. It later served as the computer room of the HMS Bounty in Star Trek IV.
The Flight Control Room overlooks the shuttlebay doors with upper and lower viewports.
A single crewperson can guide incoming and outgoing craft, assisting with low-powered tractor beams.
A look inside.
The Shuttlebay doors slide (theoretically) into pockets on each side.
Once a craft passes the atmospheric force field, internal tractor beams take over. These are controlled from the Hangar Operations booth, visible at the far end.
The Flight Deck. Alcoves on each side provide access to airlocks for EVA missions. Temporary cargo areas are marked out on the floor. Safety markings and landing lights guide incoming craft. On either side of the turbolift are spaces for the shuttle elevator pads.
The Enterprise carries 8 standard workbees, which are plugged into slots along each side when not in use. These are used for cargo handling, as well as for emergency repairs in deep space.

A typical corridor. I never get tired of this style of corridor.
The remaining decks are well under way, sadly the file had to be cut in two due to size. But, I will have external views and sections for the next part. Stay tuned!
UPDATE: I have added the bases for the nacelle pylons and some additional interior details. The LDD file has also been updated.
The hull transitions between the engineering section and the pylons were particularly tricky.
On Deck N we can now see additional frame elements. The plasma conduits have also been slightly repositioned.
From Deck O there are two access ladders leading up to the pylons.

The pressure hatch into the pylon access tube. The nacelles are almost complete, and that means the ship is almost complete!
Quoting Gabor Pauler
I never really understood how it is possible that something generates almost ten tons per square meter to withold breathable air in normal pressure, and will not damage the outflying shuttle.
You make a good point. In Dune there is a force field that permits craft to pass through a designated "gate", but it doesn't have to hold any air pressure. And in Star Trek I can accept a force field that simply holds in air pressure, like when a bulkhead blows. But to let a shuttle pass through? That's never been properly explained.
Mindblasting overall shaping and interior pictures as usual. About athmospheric force field: I never really understood in any sci-fi movies ever, how it is possible that something generates almost ten tons per square meter to withold breathable air in normal pressure, and will not damage the outflying shuttle. It is something like putting medium sized trucks on the shuttle hull in several layers...
