Title:
RELEASING DEVICE FOR STEREO PATTERN
Document Type and Number:
Japanese Patent JP3200185
Kind Code:
B2
Abstract:
PURPOSE: To recognize the overlap of equipments by using the data base of three-dimensional equipment information in which two-dimensional equipment information preserved as 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 by an isometric drawing, the data base of the three-dimensional equipment information in which the two-dimensional equipment information preserved as the coordinate of the plane of each stage, height of each stage, and connection relation between the equipments of the up-and-down stages are stored is read from an outside storage device 13, the three-dimensional coordinate of connected segments as one record is resolved, and the three-dimensional coordinate is expanded. And also, the value of the two-dimensional coordinate of a work file is calculated, set at the work file, the values of an inclination and an X-axial section are calculated, and set. Then, an overlap extracting processing is operated, which (z) coordinate value in the three-dimensional coordinate is smaller in the overlapped segments is checked, and the release processing is operated.
