Abstract: A storage medium readable by a machine, storing a design support program, the program comprising a configuration displaying step of displaying a multidimensional model having a hierarchical structure configured by hierarchically combining parts on the basis of part data that define a multidimensional configuration of part, assembly data that define a part layout or assembly data that specify a layout of other pieces of assembly data, a child model designating step of designating as a processing object, based on input information from a user, a child model corresponding to part of the multidimensional model containing part data or assembly data, and an attribute information displaying step of displaying, by referring to the part data or assembly data corresponding to the child model designated in the child model designating step, an attribute of the child model that contains a position in a hierarchical structure for an image of the multidimensional model.

Abstract: Disclosed is a technology of making a user grasp and specify a basic configuration invisible in a finally generated three-dimensional configuration in a three-dimensional CAD system for generating the three-dimensional configuration by sequentially combining the basic configurations. A solid editing method in the three-dimensional CAD system for completing the three-dimensional configuration through a process of combining a plurality of basic configurations displayed on a display screen with an operation unit, comprises a step of displaying in-the-making configurations from a first basic configuration as a start configuration down to the final three-dimensional configuration, a selecting step of selecting one of the basic configurations displayed, and a step of setting, as an edit target, the basic configuration finally combined with respect to the selected in-the-making configuration.
