There are various types of BIM software available today, each with unique advantages and diverse platform capabilities. Due to space constraints, this article focuses on several BIM platforms that currently hold significant market shares.
(1) Autodesk Revit Series
The Autodesk Revit series is a 3D architectural design software suite developed by Autodesk. It includes specialized modules such as Revit Architecture, Revit Structure, and the MEP module.
Evaluation: Revit offers a user-friendly interface, stable performance, and ease of use. Features like working sets and links facilitate collaborative design among multiple departments and users. Additionally, its built-in views are linked with the 3D model views, ensuring real-time updates and accuracy across all perspectives, significantly boosting efficiency.
However, the software’s component parameterization constraints limit its ability to handle particularly complex surface designs. Also, when the viewing angle is too narrow, modifications aren’t possible; instead, the system requires rebuilding or selecting an existing work plane to continue operations.
(2) Bentley Series
Bentley Systems, headquartered in Finland, offers the Bentley software suite. Built on the unified Bentley MicroStation platform, it integrates three main product lines: building, structure, and MEP (mechanical, electrical, and plumbing). Users can selectively load modules based on their needs, optimizing computer memory usage and streamlining component selection and operations.
Bentley excels in infrastructure design, construction, and operation, capturing a substantial market share. Additionally, ProjectWise, developed with server technology, enhances project information security and simplifies communication.
Evaluation: Similar to Revit, Bentley provides a range of software solutions for various architectural fields. However, Bentley’s applications extend more broadly into industrial sectors. Its user interface is more complex, which can make mastering the software challenging in a short time.
Key points include:
- Bentley uses a more unified file format (DGN/DWG), promoting standardization across project files, whereas Revit uses RVT/RTE files, which can complicate coordination among multiple engineers.
- Bentley supports advanced modeling techniques including mesh surfaces, solid modeling, B-Spline curves and surfaces, programmatic modeling, building relationships, and topology—similar to Autodesk 3ds Max—facilitating the creation of complex geometric models. This capability surpasses what Revit offers.
- The software stores data based on files, minimizing memory usage and enhancing speed.
(3) Autodesk Navisworks
The Autodesk Navisworks series is a powerful software suite designed for analysis, simulation, and project review. It comes in three versions: Navisworks Manage, Navisworks Freedom, and Navisworks Simulate, each tailored with different functionalities.
By integrating design data from multiple disciplines into a single project model and importing it into Navisworks, users can set parameters to detect spatial clashes and simulate construction sequencing across various specialties. This enables effective collaboration through real-time walkthroughs and annotation reviews, helping design and construction teams predict and avoid potential issues before construction begins.
Key features include:
- Browsing and Viewing Module: Offers roaming, flying, surround view, panning, zooming, and dynamic observation, allowing for real-time 360-degree views of the project.
- Rendering Tools: Includes a renderer, materials manager, and lighting manager to visualize 3D scenes in Navisworks.
- Clash Detective: Performs spatial conflict detection across integrated models from various disciplines.
- Timeliner Module: Simulates the construction process based on the construction schedule, incorporating details like start and completion times, material costs, labor expenses, and other BIM model component data in 5D (3D + time + cost) virtual construction. It also integrates with Navisworks’ Animator module to simulate the movement and installation of construction equipment and machinery.
