A calculation area including a three-dimensional (3D) product model is specified, and a plurality of cross-sectional images is cut out from the calculation area. Each cross-sectional image is divided into plural pieces of voxel data, and voxel data of a gap area of the inside of a product is generated from the plural pieces of voxel data. A 3D model of the gap area of the inside of the product is generated, and also a volume of the gap area of the inside of the product is calculated, based on the voxel data of the gap area obtained by each cross-sectional image.

There is disclosed an apparatus for supporting an evaluation of equipment operability in which simulation equipment models of design object equipment or layout object equipment are arranged in a simulation space together with simulation body-shaped models patterned after humans who may operate the equipment, and the body-shaped models are moved within the simulation space so that an evaluation of operability of the layout object equipment is supported. A reference position of a body-shaped model to be arranged in the simulation space is defined in accordance with a basic posture of the body-shaped model. When the present model is changed to a body-shaped model which is different in the body form, the body-shaped model after an alteration is arranged in the simulation space so that the reference position coincides with the reference position before the alteration.
