Research and Implement of Standardization and AutomationFramework of Construction Drawings
Wenyong Wu, Ke Jiao, Huibo Tong, Licai Wu
The key factor of BIM implementation is the standardization and automation framework of construction drawing. For pragmatic reasons, the framework should not only support basic finite element analysis, drawing and estimation software but also different versions of AutoCAD. Technically speaking, automation, individuation, interaction and platform adaptability of the framework are the keys. Automation means high drawing speed and better drawing quality; individuation means the construction drawing framework is adaptable to different ways of drawing expression; platform adaptability means the framework is compatible for other drawing software; interaction means related drawings can modify themselves when a structure component is modified. In the end of the article, the process of implementation of standardization and automation framework is introduced.

In this paper, the BIM technology is applied in the design of high-rise residential buildings, to launch analysis and research on several key technologies. A BIM-based multi-disciplinary modeling architectural form and a datum-providing method in collaborative process are introduced in the paper, and a GDAD-PCMIS collaborative management system is developed to meet the needs of multi-party collaboration. A shape-nesting plan-design module is developed, which is able to form various building plans through combining different flexible modules with the fixed modules. An application method of component part based on linkage function is proposed to ensure the unity of component detail drawings and 3D models, as well as a prefabricated component part library is established to embody the accumulation of the component parts. The cost composition of the prefabricated building is also discussed to analyze the impacts of different prefabricated component combinations on the economic benefits of the buildings. The assistive calculation software on the prefabrication rate and assembly rate is also developed to enhance the design efficiency of prefabricated high-rise residential buildings.

As is normally understood, the forward design is to generate 2D drawings directly form 3D models that conforms to the drawing specifications in each stage, where a rich family library will act as the soul. As a popular modeling software in the civil construction field, Revit acts as a platform serving for various engineering projects with 3D modeling visualization and 2D drawing representation. The Revit models are mainly consisted of elements of the family in the software. This paper starts from the family, the basic element for forward design implementation based on 3D BIM model, and analyzes the functions of existing family bank management tools and the problems existed in decentralized management families. Suggestions on the construction requirements of family bank management tools are put forward, and then demonstrated through a case study of machinery and equipment families. How to improve the maintenance and updating of family components in the operation process of building will be discussed, in order to promote the development of BIM forward design technology by point and area.

With the continuous development of computer processing capability and software functions, applications related to the BIM-based 3D design of the AEC industry been gradually popularized.There have been many practical BIM-based methods in in volume scheme selection, construction submission and concept design, construction drawing design of each specialties, 3D deepening design, and etc.However, it is still difficult to realize the BIM-based forward collaborative design in full-process and multi-professional, and the main reasons are due to the inapplicability of present BIM model storage mode for the traditional design architecture, ineffective resolution results of the BIM models, and inadequately extensive software functions due to over-dependence on foreign BIM software.This paper summarizes the current working situation, analyzes the requirements and challenges from CAD design to BIM forward design, and proposes a "digital-analog separation" BIM forward with relational database+model drawing file manager as the core.The architecture of the design platform uses the architecture to perform separate storage management of non-geometric information such as design results, school approval notes, and progress control.The unique ID values are connected to make the geometric model and non-geometric information combined into an organic whole in order to achieve integrated management.
