BIM core modeling software, commonly known as “BIM Authorship Software,” serves as the foundation for implementing BIM technology. Around the world, various software companies develop BIM modeling tools tailored to different industries, including the following:
1. Autodesk Revit (Architecture, Structure, and MEP)
This suite offers architectural design and documentation systems tailored to specific disciplines. It supports design and construction drawings throughout all project phases. At the heart of the Revit platform is its parametric change engine, which automatically updates changes made anywhere in the model. Revit is the most widely used BIM software in China and has proven to significantly improve design efficiency. Its main strengths include broad popularity, relatively simple operation, and leveraging AutoCAD’s established presence in the civil construction market, resulting in strong market performance.
2. Bentley Systems (Architecture, Structure, and Equipment)
Bentley products excel in large-scale infrastructure projects such as factory design (including petroleum, chemical, power, and pharmaceutical industries) and infrastructure sectors (roads, bridges, municipal works, water conservancy, etc.). These are clear advantages that distinguish Bentley in the market.
3. Nemetschek Group (ArchiCAD, AllPLAN, VectorWorks)
After acquiring Graphisoft in 2007, Nemetschek integrated three main products: ArchiCAD, AllPLAN, and VectorWorks. Among them, ArchiCAD is widely used in China and targets the global market with significant influence. However, its professional features (e.g., for architecture) do not fully align with the multidisciplinary integrated design institute system, limiting its potential for broader business breakthroughs.
4. Dassault Systèmes CATIA
CATIA is a leading mechanical design and manufacturing software with a near-monopoly position in industries like aviation, aerospace, and automotive. While it offers superior information management and expressive capabilities compared to traditional design software in engineering construction, it is somewhat weaker in project engineering integration.
When defining the technical roadmap for BIM core modeling software in a project or enterprise, consider the following principles:
① Autodesk Revit is recommended for civil and engineering building design.
② Bentley is suitable for factory design and infrastructure projects.
③ Selecting ArchiCAD, Revit, or Bentley as the primary tool can lead to success for specialized architectural firms.
Of course, beyond these guidelines, the requirements of project owners and other stakeholders also play a crucial role in shaping the BIM technology strategy.
