Drawing retrieval method and system

Abstract

The present invention provides a drawing retrieval method and system. The method is characterized in that: by determining a key part of the construction in the three-dimensional model of the construction project, the technicians of the construction unit and the designers of the design unit can be coordinated, and uncertainty of the key parts of the construction in the 2D drawing can be found as much as possible before the construction; and the 2D detail drawing of the key parts of the construction and the corresponding 3D detail models are generated according to the construction parameters, and the association relationship between the 3D image and the 2D image is established, so that the accuracy of the expression of the construction design can be improved, the degree of control of the complex nodes by the technicians on site can be improved, the calibration ability of the construction design can be improved, workers can view the drawings in a facilitated manner, the understanding canbe improved, accuracy of understanding of the construction workers on the construction plan of the construction project can be improved, the accuracy of the operation can be increased, the re-work isreduced, project quality and corporate profits can be ensured, and convenient conditions are created for acceptance of concealed construction projects.

Description

technical field [0001] The invention relates to a drawing retrieval method and system. Background technique [0002] The technical disclosure of the current construction is usually based on the two-dimensional construction blueprint, combined with the design disclosure documents provided by the design unit, and then using text descriptions to express engineering characteristics, technical requirements, operation methods, quality indicators, construction measures and other engineering information. Existing problems and deficiencies: [0003] 1) Since the design disclosure provided by the design unit is in the form of text. Therefore, it is easy to cause differences in text understanding between the technicians of the construction unit and the designers of the design unit. In addition, the drawings provided by the design unit are two-dimensional drawings, and the design information expressed by the two-dimensional drawings is not complete. Therefore, In many cases, the desig...

Problems solved by technology

[0005] The purpose of the present invention is to provide a drawing retrieval method and system, which can prevent the design information expressed by the existing two-dimensional drawings from being complete, resulting in differences in design intentions between designers and construction technicians, resulting in the problem of construction rework
