Patent ID: 7529649

Claim:
A computer-implemented system for designing an interior section of a passenger vehicle to accommodate objects for the interior section of the passenger vehicle, comprising a database comprising a digital definition of the interior section of the passenger vehicle and parameters related to the objects; a computer-aided design system configured to display a visual model of the interior section of the passenger vehicle; a user interface capable of receiving user input from a user reflecting a first change to the interior section of the passenger vehicle; a processor responsive to the user input by using said digital definition and said parameters to determine automatically whether a second change to the interior section of the passenger vehicle is necessary because of the first change to the interior section of the passenger vehicle, and execute automatically the second change to the interior section of the passenger vehicle by updating said digital definition and execute automatically changes to the entire interior section by updating said digital definition based on the other changes in the interior section; and a means for zones being arranged in a hierarchy wherein each zone represents a smaller portion of the vehicle, and there is at least one or more smaller zones inside a larger zone.
