An information processing apparatus includes a processor configured to generate, in a simulation space, a rectangular parallelepiped surrounding a target part among a plurality of parts. The target part is taken by a human body. The rectangular parallelepiped has surfaces in contact with a maximum outer shape of the target part. The processor is configured to identify, among the surfaces of the generated rectangular parallelepiped, surfaces other than a surface in contact with a part different from the target part, and select combinations of two surfaces among the identified surfaces. The processor is configured to identify, among the selected combinations, a combination which satisfies a condition that a vector from a point of a first finger to a point of a second finger penetrates the rectangular parallelepiped when the two surfaces in the combination are taken by the two fingers. The two fingers are included in the human body.

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.

A height-limited-area-information creating device creates a clip plane on a base plane of a printed circuit board, and sets a view so that an image faces the base plane and a normal to the base plane represents a depth direction of the image. According to the view, a three-dimensional image of a chassis-side component is created. The base plane is divided into unit areas, and one of the unit areas is selected. Coordinates of vertices of the selected unit area are transformed to screen coordinates to acquire a component and a polygon at the position of the screen coordinates. Distances from respective four vertices to the polygon are calculated as height, and a minimum value is determined as a maximum height for the unit area.

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.
