BIM has five key features: three-dimensional visualization, simulation, collaboration, drafting, and optimization.
One major breakthrough of BIM compared to traditional graphic design is its 3D visualization feature. BIM integrates conventional 2D graphic design into a visual 3D model format, providing more comprehensive information from the model. The other four features build upon this visualization foundation. Simulation and collaboration aim to resolve issues caused by poor communication and information gaps. Drafting and optimization utilize the 3D models to simulate and detect potential clashes between different disciplines early on, enabling problems to be identified and addressed promptly, which facilitates smoother construction progress later.
Commonly Used Basic BIM Software
While data exists on its own, mining and storing it requires specialized tools. BIM can be viewed as a data repository, and the related application software serves as tools for discovering and analyzing this data. With technological advancements, the range of commonly used BIM software continues to grow, along with the diversity of functions they offer.
Currently, leading BIM modeling software internationally includes Autodesk Revit, Bentley, and Tekla Structures. Each software focuses on different functionalities: Revit and Bentley are primarily used for multi-disciplinary modeling, whereas Tekla specializes in steel structure modeling.
As BIM technology gains wider adoption in China, traditional engineering software manufacturers have also started developing BIM solutions. These typically come in two forms: first, independently developed platforms such as Guanglian Da and PKPM; second, secondary development tools that enhance existing foreign software, like Guangxia GSRevit and Pinming HIBIM. Besides modeling software, there are also BIM-related scheduling tools, clash detection software, and walkthrough rendering applications.
