Accurate, or honest about why not. The walls are the heavy lines on your sheet — the architect's own — with door and window gaps left where they're drawn; nothing is redrawn or filled in by guesswork. Scale comes from the sheet's own note ("1/4" = 1'-0""), from a scale you choose, from two points you calibrate against a known dimension, or from the building's overall width — in that order of confidence, shown on the preview. Walls thinner than a printer can make at the model's scale are widened to exactly the printable minimum and the amount is stated. Each floor is one flat print; stacks align on two posts and pegs. Every model is checked by a person against the plans before it prints.
