What does BIM mean to many people today? I’d like to share some of my own thoughts. But first, what exactly is not considered BIM technology? Today, the BIM Architecture Training Network editor will share some insights on this topic.
BIM is a popular buzzword often used by software developers to describe the capabilities their products offer. Because of this, the definition of BIM technology has become somewhat variable and confusing. It might be easier to clarify by examining modeling solutions that do not use BIM technology. These include tools used to create the following types of models:
First, models that contain only 3D data with little or no component attributes. Such models are primarily used for graphic visualization and lack intelligence at the component level. While they offer good visual effects, they struggle or fail to support data integration and design analysis. For example, Google’s SketchUp is very useful for rapid development of architectural schematic designs, but it has limitations when it comes to other types of analysis. This is because it recognizes only the geometry and visual appearance of components, without understanding the design objects themselves.
Second, models that do not support parametric operations. These models define components but cannot adjust their positioning or scale due to the absence of parametric information. This makes modifications labor-intensive and prone to errors, as the model cannot automatically prevent inconsistent or incorrect views.
Third, models composed of multiple 2D CAD reference files that must be combined to represent a building. Compared to component-based models, these cannot guarantee that the resulting 3D model is feasible, consistent, or reliable. Although it is possible to change dimensions in one view, these changes do not automatically propagate to other views, leading to errors that are difficult to detect.
In summary, the above points reflect some of the BIM Architecture Training Network editor’s views on what does not constitute BIM technology. We encourage everyone to share their own opinions and contribute to this discussion.
