Abstract:
As same as what the game Minecraft embodies, Voxel-based Architectural Space Analysis(VASA) is a method of decomposing a model into cubes of a certain size. It transforms geometry or STL files and meshes from Revit into voxel models, which can then be used to perform a number of analyses on the 3D voxels, such as path analysis, daylight analysis, view analysis, acoustic analysis, etc. The voxel-based approach enables building space analysis to construct more complex scenarios and generate more accurate analysis results, as well as integrate voxel analysis into derivative design workflows.

Abstract:
MEP engineering has the characteristics of numerous specialties, diverse types of components and complex geometric relations, etc. And different types of components have different calculation rules, and some dedicated metering software has different degrees of restrictions in application, so the accurate calculation of the mechanical and electrical installation engineering quantity has always been the concern in the industry. Therefore, this article compares the similarities and differences between Revit software and the calculation rules in my country's Standard Method of Measurement for General Building Services Works (GB50856-2013). Adopting Revit plug-in development, the article reformulates the calculation rules by using C# computer programming language. The developed plug-in solves the problem of inaccurate quantities of components at some special-shaped fittings, and the interface is simple to operate. The quantities are exported in accordance with the specifications. Meanwhile the edited mapping table is matched with the bill attributes to the components one by one. Finally, the table of component detail and bill of quantities is summarized and exported. Through a practical engineering application, the engineering quantity derived is compared with the calculation results of the existing e-mechanical and electrical calculation plug-in in the market. The accuracy basically meets the requirements, and the rapid calculation under the 3D model is realized, which provides a new idea for improving the efficiency of the measurement and valuation of mechanical and electrical installation engineering.

Therefore, according to the requirements of the design code for beam-column joints of steel structures and combined with design and construction experience, a parametric family member model of beam-column joints, beam-beam joints, and column foot joints of steel structures based on the Revit family is established. The Revit application programming interface and C # code are used to identify the location of the target node in the model. The established steel structure node family model is selected and loaded into the actual project model to realize the automatic generation of a parametric steel structure node model. This method can quickly generate the steel structure node model, solve the problem of time cost in deepening the design of nodes, and greatly improve the work efficiency of designers.

Abstract:
It is inevitable to convert the version of Revit model during the modelling, application, and management stage of BIM implementation due to the flexible application scenarios. However, the industry is still lacking solutions to downgrade Revit models. Through the secondary development of Revit, this paper customized the tools to convert the version of Revit model. The mechanism is that it collects and stores the key information of major components as an intermediate file format, then adopt another version of Revit to read the intermediate file for creating corresponding components by calling API to achieve the version exchange., Therefore, the model version is downgraded for using purposes. Taking Shandong Jinan Shulan Hospital project as an example, this program validated that the proposed method for downgrading Revit model can significantly decrease the time consuming.

With BIM technology in the sustainable implementation of China Construction Eighth Engineering Division Co., Ltd., the BIM data created by construction projects is increasing, and it is more and more difficult to control the accumulation of The control of BIM data is becoming more and more difficult. Developed with independent control of intellectual property based on BIM collaborative management platform, China Construction Eighth Engineering Division Co., Ltd., in helping the site at the same time, it realizes centralized control of BIM data and various engineering and construction data created by each unit. CIM is based on three-dimensional city based on urban spatial geographic information, it is an extension of BIM in the urban context. This paper studies the data integration application of BIM and CIM platform, and sort out the data resource standards on the basis of BIM collaborative management platform. Based on the BIM collaborative management platform, this paper composes the data resource standards, and realizes the high efficiency integration from BIM to CIM through light processing, data-mode separation and data fusion. Therefore, the integration from BIM to CIM will be seamless and effective.

Abstract:
The 14th Five-Year Plan has put forward the new requirement of "accelerating digital development", and it is urgent for the construction industry to realize digital transformation and upgrading. BIM Technology is the bottom data information of building digitization. BIM Technology is widely used in rerecord design at present stage, which is contrary to the original intention of digital construction and hinders the rapid development of digital construction. Therefore, the promotion of BIM top-down design is the key to the digital information construction of architectural design industry.Currently, BIM positive design is being gradually implemented by individual large design institutes and large real estate enterprises, but its experience has not been widely popularized. This paper summarizes the results of BIM positive design in design institutes through the practice of construction drawing positive design of specific projects, and provides experience for the development and promotion of positive design and digital transformation and upgrading of construction enterprises.
