What is the most important feature of BIM today? What's the point? When it comes to BIM, the first thing that comes to mind is the model or software. In my opinion, BIM has many characteristics, but the most important ones are the following!
First, the 3D model is visualized.
The traditional two-dimensional graphics theory only lacks the imagination of overlapping elevation of components, and needs people with rich professional experience and drawing reading ability to imagine its three-dimensional shape. Interface problems are not intuitive and easy to detect, which often leads to trouble in communication and coordination and ignores potential problems. The 3D visual characteristics of BIM can present the architect's design concept truthfully, so that project participants can eliminate communication errors and improve the efficiency of project members' coordination and communication.
Second, parametric design.
BIM building model consists of parameterized components, such as columns, beams and walls built into the software or model components created by users themselves. Each component has parametric characteristics, and parameters can be used to define dimensions, or to add fields of custom parameters to create components for information search and management. When modifying component parameter information, the model will correct all changes in the model at one time.
Third, two-way connection.
Parametric design has the characteristics of synchronous change. When modifying component dimensions and information, it can also be displayed in different drawings at the same time, which can avoid the risk of confusion caused by inconsistent information. Because the component label is displayed by reading the parameter operation, the label information can also be automatically modified when modifying the parameter information to ensure the consistency of the construction drawing information generated by the model.
Fourth, work together.
BIM enables construction professionals to enjoy project information and carry out collaborative work through the network without being limited by time and place, provides an exchange platform for professional modeling and integration, and solves the problems of complex interfaces and lack of standards and integration procedures for different types of work. sd.yd 1 19.cn
Verb (abbreviation for verb) integrates information.
In the traditional construction process, information is transmitted asynchronously. Due to the gap of time transmission, scattered engineering drawings and huge amount of information in signed documents, the process is often difficult to integrate. Therefore, through the concept of BIM single model, the latest correct information feedback can be corrected to the model, which can confirm the decision-making results of real-time information, improve the information confusion caused by traditional information integration and transmission, and make relevant information completely preserved and integrated.
Application of additional functions of intransitive verbs
BIM does not refer to several specific softwares. In addition to modeling software, there are many application softwares with different functions, which can make the completed BIM model apply more additional functions, such as generating construction drawings from the model, using computers to check whether there is enough space and whether objects interfere and collide, calculating detailed lists of quantities and output, conducting construction simulations such as 4D schedule management and dynamic line simulation, so as to study alternatives of value engineering, as well as structural strength analysis and energy and acoustic energy analysis, so as to assist intelligent green building design, earthquake-resistant houses and other applications.
