Problems solved by technology

A desktop computer cannot meet this requirement
However, if the BIM model needs to be displayed on the PAD port, it is limited by the performance of the PAD, so the BIM model must be lightened.

Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0039] A method for lightweighting a BIM model according to the present invention comprises the following steps:

[0040] Step 1: Export the first BIM model as the second BIM model, and save the component color and material information of the components in the first BIM model; among them, the configuration requirements for running and displaying the second BIM model are lower than those for running and displaying the first BIM model configuration requirements; for example, export the first BIM mod...

Abstract

The invention provides a method and a system for lightening a BIM (Building Information Modeling) model. The method comprises the following steps of exporting a first BIM model into a second BIM model and storing component color material information of a component in the first BIM model, wherein configuration requirements for operating and displaying the second BIM model are lower than those for operating and displaying the first BIM model; simplifying a solid mesh of the second BIM model and processing boundary representation to obtain a third BIM model; rendering the third BIM model according to point-line-face information and the component color material information. According to the method and the system, the BIM model can smoothly operate on a mobile terminal after being lightened; economic benefits are greatly improved; social resources are saved; the method and the system not only is perfectly applied in the constructional engineering, but also is applicable to other BIM working platforms and has guiding and leading effects on the future industrial development.

Description

technical field [0001] The present invention relates to computer graphics, computer-aided design and interactive technology, in particular to a method and system for reducing the weight of a BIM model. Background technique [0002] BIM is the abbreviation of Building Information Modeling (Building Information Modeling). It is a kind of building life cycle information management technology. It can digitize building information and use this digital information model as a basis to simulate construction at various stages. It has five basic characteristics of visualization, coordination, simulation, optimization and plotting. [0003] BIM is a brand-new method of architectural design, construction, and management. Based on three-dimensional digital information technology, all data in planning, design, construction, and operation stages are included in the 3D model, allowing the entire life cycle of the building to When using the model, workers at any stage in the process can mak...
