Popular BIM core modeling software includes Archicad, Bentley, and Revit.
1. Archicad
Developed by Nemetschek in the 1980s, Archicad is a 3D design software tailored specifically for architecture. It utilizes the GDL language and offers robust 2D and 3D conversion features, with unique strengths in document management and drawing capabilities.
Advantages:
- Excellent compatibility across Mac and Windows platforms, enabling quick conversion of 2D DWG drawings into 3D data files.
- Strong drawing capabilities: BIM forward design automatically generates plans, elevations, and sections from the model, allowing for synchronized modifications. CAD layer functionality aligns well with user habits.
- Good performance and speed with relatively low hardware requirements.
Disadvantages:
- Modeling complex or irregular surfaces can be inconvenient.
- While architectural modeling is powerful, its structural and equipment specialty features are limited and used less frequently.
- On large projects, global parameter rules may cause system scaling issues, reducing efficiency.
2. Bentley
Created by Bentley Systems in 2004, this software supports architecture, structural engineering, HVAC, electrical, plumbing, collision detection, and more. Its collaborative platform and various modules make it suitable for a wide range of building and municipal infrastructure projects.
Advantages:
- A unified collaborative management platform enhances coordination between disciplines, improving efficiency and reducing costs.
- Powerful modeling capabilities enable true 3D, detailed modeling, and precise spatial positioning of pipeline structures.
- Good file compatibility with lightweight models, making it easy to use on mobile devices.
Disadvantages:
- The software is complex to operate, with limited online learning resources and minimal promotion, making it challenging to master quickly.
3. Revit
Originally developed by Autodesk in 2003, Revit is divided into three main components: Revit Architecture, Revit Structure, and Revit MEP. It provides extensive family libraries and is one of the most widely used BIM modeling software.
Advantages:
- Comes with rich family libraries that support flexible modeling through system families, built-in families, and loadable families, all of which can be accessed and modified as needed.
- Parameter-driven modeling enables management of model data throughout BIM construction stages, improving accuracy in quantity takeoffs.
- Plan, elevation, and section drawings are linked and updated automatically, reducing repetitive tasks and minimizing errors.
- Includes collision detection for visual inspection of errors, omissions, clashes, and defects, helping to reduce correction costs.
Disadvantages:
- Revit eliminates the traditional AutoCAD layer concept, requiring time for modelers and cost controllers to adapt.
- Modeling complex surfaces is relatively complicated, and the software demands higher hardware performance, which can impact speed.
