The BIM model is a comprehensive database containing extensive building information, created using BIM technology and related software. It goes beyond simply representing points, lines, and surfaces as in CAD models, and it is more than just the impressive visual effects of 3D models. Instead, BIM focuses on the integration, analysis, and processing of real building data. Today, let’s explore the key functions of BIM models.
1. Extracting Geometric Parameters
Geometric parameters are essential data that describe objects in two- or three-dimensional space, defining their position, size, and shape. BIM tools make it easy to extract or modify these geometric parameters. Furthermore, these parameters can be used for spatial logic tasks, such as automatically sorting lifting programs by direction, extracting object coordinates, or calculating the total length of required steel bars.
2. Extracting Object Parameters
One of the main differences between BIM models and traditional 3D models is that each geometric object in a BIM model carries unique parameters that describe its specific behavior or characteristics. While 3D models often distinguish objects only by visual differences, BIM models clearly identify objects by their internal parameters, such as names or categories. These object parameters are crucial to BIM, though their descriptions can vary by region. Extracting and analyzing these parameters within BIM software is vital for further processing, often using spreadsheet tools like Microsoft Excel.
3. Automating Repetitive, Large-Scale Tasks
Building a BIM model frequently involves many repetitive and extensive tasks, such as entering continuous reinforcement data or creating identical structural components. Previously, these tasks were manually performed by engineers, which was time-consuming, monotonous, and prone to input errors. BIM software allows users to automate these repetitive tasks, reducing mistakes, speeding up workflows, shortening project timelines, and improving overall quality.
