@ blssdwlf - I see and did a recalculation. We have Shatner's body height and we see how wide the corridor walking floor area (the innermost two parallel lines in the studio set blueprint
) is in relation to Mr. Shatner (I arrived at 132 cm).
Now I arrive at an approximate width of 5.4 meters for the deck platforms surrounding the intermix shaft below the main engine room level.
At 5.4 m (305 m Enterprise
O.L.) the port and starboard side exterior hull would be too thin, so obviously a 6.3 m connecting dorsal pylon width (355 m Enterprise
O.L.) would be the better option, but it looks like that shaft could still fit into the connecting dorsal pylon.
