These days you can find all sorts of artwork on the Millennium Falcon, including deck plans. But, I wonder how much was done for the very first movie back in the 1970s. Specifically, I am curious about how the original interior sets harmonized with the exterior mockup(s) and "flying" models, and whether the interior spaces depicted on film could have actually fit in a logical layout within the envelope of the craft as seen from the outside.
As an example of the TV magic underlying my point, I refer to the British soap opera Coronation Street and its iconic Rovers Return pub. Between 1982 and 2014, there were interior sets representing various spaces within the pub, both in front of and behind the bar, and an exterior outdoor set. It was fairly easy to notice that the interior floor plan as depicted couldn't possibly exist within the footprint of the pub's exterior - rooms such as the kitchen would be out in or even on the other side of an adjacent street, and washrooms would occupy much of the neighbor's main floor.
There is, for example, this Millennium Falcon deck plan which I assume was drawn up retrospectively, and appears to pull it all together more-or-less logically. Was this (or other artwork of this sort) actually created for the original movie (for model/set construction)? If not, was anything done at the time which would have mapped out the interiors in a way that would have actually fit all those spaces into the ship as it appeared to stand in the Mos Eisely spaceport, etc..
