BIM three-dimensional building model display method based on Web terminal

Abstract

The invention relates to a BIM three-dimensional building model display method based on a Web terminal, belongs to the technical field of building industry information, and solves the technical problem of BIM webpage terminal display. The method comprises the following steps: firstly, establishing a three-dimensional building model in Revit software by using an engineering drawing, secondly, extracting three-dimensional model information in the form of a Revit plug-in and generating an XML intermediate file, and finally, importing the XML file into a browser to be analyzed by using a Three.jsframework, thereby realizing the display of the three-dimensional model at the Web terminal. The invention provides the BIM three-dimensional building model display method based on a Web terminal, andprovides a method for analyzing an XML (Extensive Markup Language) model file by a browser by taking BIM webpage end display optimization as a target and combining a WebGL technology and a BIM technology, so as to realize seamless import of model data and ensure complete display of a model. According to the method, the lightweight and visualization of the BIM model can be better realized, and theuse convenience and interactivity of the building model are improved, so that the engineering application of the BIM technology is promoted.

Description

technical field [0001] The invention belongs to the field of construction industry information technology, and specifically relates to a method for displaying a BIM three-dimensional building model based on a Web terminal. Background technique [0002] Since the late last century, the popularity of computer-aided design (CAD) has led the first wave of informatization and digitalization in the construction industry. With the development of the construction industry, traditional CAD technology cannot solve the problem of multi-party information interaction in the whole life cycle of the building. The low efficiency of information sharing leads to the low level of project management and hinders the development of the construction industry. The development and application of building information management model based on 3D visualization technology has become inevitable. [0003] With the advent of the "Internet +" era, BIM technology has become the hottest building information...
