Embodiments of the invention allow users to generate and maintain space objects in a computer-aided design model representing regions bounded by a set of drawing elements included in the model. The space object contains the geometry of such a bounded region and may be used to calculate values such as area and volume associated with the region. Additionally, each space object may be associated with the set of drawing elements bounding the region represented by the space object such that any changes to one of the associated bounding elements causes the geometry of the space object to be updated automatically to reflect these changes. Areas and volumes calculated from the space object geometry may conform to established standards regarding the calculation of gross, net and useable areas of a building or other structure.

A repeatable patient-specific measurement technique. The process employs common anatomical reference points to guide the individual performing the measurements. The measurements taken are logged into a database using a standard format. A volume corresponding to the area measured is then calculated. The series of measurements can be accurately repeated during subsequent evaluations of the individual. Subsequent volume calculations are also made so that the volume of the measured region can be tracked over time. The volumetric information is then used to evaluate certain individual-specific criteria such as efficacy of weight management plan. Computer software will also present the data in a variety of numerical and graphical formats that are useful to the individual.

A system and method is provided for analyzing the movement of an object. The system is comprised of a sensor that is coupled to a processor that is configured to generate a volume that corresponds to a predefined area and the location of the object. The sensor detects the movement of the object and determines if the object's movement is within the volume. If the movement is within the volume, then an information channel is created between the volume and the user defined algorithm. The movement is then compared with the requirements of the user defined algorithm and accepted if the movement meets the requirements. Otherwise, the object's movement is discarded if the movement is not within the volume or does not meet the requirements of the user defined algorithm.
