3D object interference check method and device

Abstract

Abstract PURPOSE:To facilitate the interference check of a three-dimensional object by constituting the title device so that a display of a position relation of a complicated three-dimensional shape object can be replaced with a simple graphic display such as a two-dimensional sectional graphic which has been generated by an arbitrary insertion surface. CONSTITUTION:The title device is provided with an input part of object shape data consisting of an instructing part 1 and an instruction data analyzing part 2, a storage part consisting of a main storage device 4 and an external storage device 6, and a display part 3, and the main storage device 4 is provided with processors 5, 5' and functions as an arithmetic part, as well for generating three-dimensional shape data from shape data of the object. In this state, a state that plural objects whose interference check is executed have been placed is expressed by three-dimensional shape data for forming the shape constitution surface of the object, an arbitrary surface is inserted into a state that the object has been placed and an intersection line of the insertion surface and the shape constitution surface of the object is derived by an operation, a position relation of each three-dimensional object is replaced with a position relation of each two-dimensional sectional graphic shown on the inserted surface, and the sectional graphic is displayed on the screen. In such a way, whether an overlap exists or not can be read from on the screen.
