Although the concept of BIM technology is very good, it encountered a problem when it landed in the domestic construction industry-focusing on model making and treating BIM as a simple three-dimensional modeling technology, while the truly valuable BIM data consumption has not been widely used.
The reason is closely related to the inconvenience of file browsing and data extraction of BIM model. The BIM model of a project is often above 1G, which needs to be opened by professional modeling software. Both file transfer and model browsing are limited by computer configuration and network speed, and the efficiency is very low.
Moreover, most domestic mainstream BIM models use foreign commercial software. In order to extract the attributes and data in the model, it is necessary to use the support platform of foreign manufacturers, which has high cost, low localization and poor data security, which seriously restricts the further promotion and application of BIM in China.
With the transformation of the construction industry to the intelligent direction, BIM technology is an indispensable part, and effective methods are needed to overcome the application problems of BIM technology.
BIM engine is a feasible method. BIM engine can transform BIM model into lightweight, extract the complete data of the model, effectively connect the production and use of the model, and make BIM no longer stay at the level of "seeing" and really "use" BIM.
When choosing a BIM light engine, we should focus on the following factors:
1, whether it supports the mainstream file format of engineering construction industry;
2. Whether the component and attribute information in 2.BIM model is completely extracted;
3. Whether the online browsing of the large model is smooth;
4. Can support low-profile display terminals;
Data parsing
BCoreBIM engine supports the analysis of more than 10 mainstream file formats in the construction industry, such as. rvt，。 ifc，。 skp，。 dwg，。 dxf，。 Osgb and so on. , compatible with the merger of multi-disciplinary and multi-software achievements, and realize the unification of data formats.
BCoreBIM engine can realize the full data extraction of BIM model and CAD drawings.
For BIM model, BCoreBIM engine supports the extraction of general data such as project, model, elevation, type, system and component. It also provides the extraction of 3D axis network, space, holes, port connections and other feature extension data, and can export a complete attribute list. Provide data extraction capabilities for business scenarios such as cost material calculation and model review, so that BIM models are not only "visible" but also really useful.
For CAD drawings, BCoreBIM engine can not only analyze data at the level of graphic elements, but also export the layout space and model space of drawings, and support splitting drawings by layers, blocks and borders.
Graphic visualization
BIM applications are most worried about frequent jams and crashes when browsing models and drawings on the Internet. If it can't run smoothly, even if the application has more functions and dazzling effects, it is difficult to use it in actual projects.
BCoreBIM engine provides graphical visualization services for developers, and online browsing and interactive operation of BIM models, CAD drawings and GIS models can be realized only by calling graphical API.
With the excellent lightweight technology of BCoreBIM engine, most drawings can be loaded in 1 second during the second loading, whether it is ordinary computers on the construction site, mobile phones or tablet computers. Even if it is a super-large model, online browsing will not be stuck or flashing, so don't worry that the application won't run.
