摘要

PROBLEM TO BE SOLVED: To support creation of a decomposition figure of a three-dimensional CAD.SOLUTION: One component among plural components included in a target assembly of decomposition is selected. A three-dimensional CAD display device 100 creates a first projection figure group in which the selected component unit is projected in plural directions, and a second projection figure group in which the target assembly is projected in the plural directions. For example, the three-dimensional CAD display device 100 identifies a projection direction where similarity of a shape or area of the component is the highest and has same projection direction between the first projection figure group and the second projection figure group. The three-dimensional CAD display device 100 sets the distance between an assembly when a decomposition image img is displayed and the taken component on the basis of the distance according to the size of the component. The three-dimensional CAD display device 100 disposes the taken component in a direction opposite to the identified projection direction, when the decomposition image img obtained by taking out the selected component from the target assembly is displayed.
