Traditional 2D CAD designs deliver and submit design results by providing the owner with floor plans, elevations, profiles, detailing, and design drawings, material sheets, and design drawings. The most common mistake in the traditional two-dimensional CAD design is that the information transmits errors between various complicated planes, facades, and profiles, and as for the collisions between the drainage lines, the displacement can be said to be endless. With the continuous emergence of landmark buildings, complex architectural shapes and spatial relationships, huge volume of design projects, the traditional two-dimensional CAD design methods in the design and coordination of the problem is particularly prominent.
This design approach allows each project has large and small, hundreds of pieces of design drawings, the entire design, each sheet is a relatively independent, separate components. These separate, separate components. Without a centralized repository that effectively integrates all information to ensure data integrity, fragmented information must be relied upon by skilled technical engineers to be interconnected to become an understandable whole. Therefore, how to ensure the coordination of various design contents and various professions, and how to make the design intent communicate smoothly, it is always an arduous challenge. Today's increasingly demanding project integration and collaboration are undoubtedly the biggest obstacles to improving project integration and collaboration.
The total design as a digital database rather than a separate document, will greatly promote the development of the industry. In the case of BIM, the project's central database is the central repository for all the physical and functional features of the building project. All of the building's entities and functions are stored in this database, opening the door for smooth exchange of information between project team members and their technical tools, making it possible to improve project integration and collaboration.
BIM provides three-dimensional dynamic visual design, the past line-style components to form a three-dimensional three-dimensional physical graphics display in front of people. Such as steel structure construction equipment (water supply and drainage) between the professional equipment, pipelines, etc. can be intuitive three-dimensional renderings, you can optimize the design, make better use of building space, effectively avoid the pipe between the professional "fight" Phenomenon, improve cooperation and coordination between various professions. The problems can be found at a glance and solved in time, reducing the occurrence of "errors, omissions and deficiencies" among drawings of various types of work
