Title:
RELEASING DEVICE FOR STEREO PATTERN
Document Type and Number:
Japanese Patent JP3200186
Kind Code:
B2
Abstract:
PURPOSE: To recognize the overlap of equipments by using the data base of three-dimensional equipment information in which the two-dimensional equipment information of the coordinate value of the plane of each stage of a building, height of each stage, and connecting relation between the equipments of up-and- down stages are stored.
CONSTITUTION: When a terminal equipment 11 instructs a host computer 10 to release the equipment information, the data base of the three-dimensional equipment information in which the two-dimensional equipment information of the coordinate value of the plane of each stage, height of each stage, connecting relation between the equipments of the up-and-down stages are stored is read, the three-dimensional coordinate of connected segments as one record is resolved, the three-dimensional coordinate is expanded, and the three- dimensional coordinate is converted into the two-dimensional coordinate. Next, the values of the inclination and X-axial section of a work file are calculated, and set at the work file. Then, an overlap extraction processing is operated, which Z coordinate value in the three-dimensional coordinate is smaller in the overlapped segements is checked by an overlap fore and aft discrimination processing, and the release processing is operated.
