Constructiong method of highway engineering BIM parametric modeling platform

Abstract

The invention discloses a construction method of a highway engineering BIM parametric modeling platform. The method refers to a method for quickly creating, calculating, analyzing and applying a BIM (Building Information Model), and comprises the following steps of: 1) establishing a visual programming engineering data structure system based on a highway engineering design full period, embedding ahighway engineering BIM standard, and flexibly defining an aggregated and derived instantiation logic relationship among engineering entity components; 2) realizing complex and heterogeneous modelingcapability through an open-source geometric modeling class library, performing engineering database management by taking a model decomposition structure as a hub, and realizing collaborative design,storage and management of a modeling body and construction information; and 3) performing three-dimensional display and information circulation based on the plug-in, the mainstream design platform andthe geographic information system, and realizing application in highway engineering design, construction, maintenance and operation stages.

Description

technical field [0001] The invention relates to BIM technology, geometric modeling technology, and graphics rendering technology, in particular to a technical method for fast modeling of BIM models and association with engineering structures. Background technique [0002] BIM technology is an engineering information application technology based on the development and integration of modern information technology and computer technology. By using digital technology to store and transmit engineering structures and structural features, it can realize the intuitive expression of 3D models and the integration of engineering design, construction, maintenance, and operation management. The information transmission and sharing and work collaboration in the whole life cycle can effectively recommend the informatization construction of engineering construction projects. [0003] Although foreign mainstream BIM software has strong modeling capabilities, there is still a running-in perio...

Problems solved by technology

[0006] The present invention provides a method for constructing a BIM parametric modeling platform for highway engineering. The method effectively solves the problem that BIM modeling software cannot meet the needs of rapid creation of high-precision BIM models for all majors of highway engineering, the association between BIM models and engineering structure systems, and the BIM parametric components. The problem of non-uniform standards realizes the creation of engineering structures based on industry BIM standards and generates model decomposition structures; the parametric BIM model automatically associates and controls the parametric modeling behavior, and realizes the modeling of arbitrary complex modeling bodies, which can be applied to the entire road engineering different phases of the cycle
