Core modeling software is essential for creating three-dimensional models of components, enabling visualization and simulation by inputting relevant parameters. Additionally, the detailed information collected is stored and utilized for basic analysis. Popular modeling software internationally includes Revit, Bentley, ArchiCAD, CATIA, and others. These tools serve as the foundational information sources for BIM (Building Information Modeling) systems, each offering unique features.
Revit holds the largest market share in the BIM software arena, supported by Autodesk’s strong technical team and extensive user community. It maintains its leadership with strong user loyalty, especially from AutoCAD users. Revit’s BIM software is divided into three main series: Revit Architecture for building modeling, Revit MEP for mechanical, electrical, and plumbing systems, and Revit Structure for structural modeling. Its strengths include user-friendly software design, ease of use, and excellent integration with AutoCAD. Users benefit from access to a vast range of technical resources and third-party family libraries online. The bidirectional linking between views and the 3D model allows real-time information updates, reducing repetitive work and enhancing accuracy. Additionally, 3D walkthroughs based on defined paths improve visualization and facilitate better communication and coordination among stakeholders.
The Bentley series comprises a diverse range of modeling and analysis software tailored to various disciplines. This includes Bentley Architecture for architectural design, Bentley Building Mechanical Systems for HVAC and plumbing, Bentley Facilities for electromechanical equipment, Bentley Generative Components for complex geometric modeling, Bentley Building Electrical System for electrical engineering, Bentley Powercivil for site modeling, and Bentley Interference Manager for collision detection. These tools are highly specialized with strong data and platform consistency. Bentley’s BIM tools for infrastructure sectors—such as petroleum, power, municipal engineering, and bridges—are particularly powerful and capable of meeting diverse modeling needs during the design phase. However, the software is known for its complexity, steep learning curve, limited third-party object libraries, and poor interoperability across systems, which often leads to it being used in isolation.
ArchiCAD, developed by Graphisoft since the early 1980s and acquired by Nemetschek in 2007, revitalized its focus on Mac systems but still holds a relatively small market share in BIM. ArchiCAD offers flexible components, strong support for energy consumption analysis, and sustainable design applications. Its user interface is intuitive and user-friendly. However, due to an outdated engine, limited parameterization, and weaker surface modeling capabilities, it underperforms in areas such as project management compared to other BIM software.
CATIA, developed by Dassault, is primarily used in aerospace and automotive industries. It features a powerful modeling platform with advanced surface modeling capabilities and excellent support for large models, allowing modeling without segmentation. CATIA is highly respected in its specialized fields, but its steep learning curve, high costs, and narrow application scope limit its broader adoption.
