BIM technology implementation and the creation and use of BIM models are inseparable from BIM software. Rather than referring to a single, all-encompassing software, BIM software is a general term encompassing various programs designed to address different practical challenges and needs in engineering. Based on their purpose, BIM software can be categorized into two main types:
1. Core Modeling Software
The BIM model lies at the heart of the technology, and many applications rely on these models to operate. Core BIM modeling software includes Autodesk Revit, Bentley’s suite (such as AECOsim Building Designer), Graphisoft’s products (like ArchiCAD), as well as Dassault’s CATIA and SolidWorks.
2. Specialized BIM Software
Throughout the entire lifecycle of engineering and construction projects, a variety of specialized needs arise. To address these, software developers have created numerous professional tools, including design scheme software, calculation and analysis programs, and construction and operations management applications.
Secondary development in BIM software involves customizing and modifying existing software functionalities to expand capabilities and meet specific engineering requirements. Given the complexity of BIM and intelligent building applications, relying on a single powerful software solution is often insufficient. Therefore, enhancing the scalability and interoperability of BIM platforms and software is essential.
As understanding of BIM software deepens and engineering challenges grow more complex, secondary development has become a key focus in BIM education and application. It is widely used to tackle practical problems such as rapid modeling, information management, and data exchange, ultimately boosting work efficiency and reducing project timelines.
