In parametric BIM, how are objects represented?

In parametric Building Information Modeling (BIM), objects are represented by parameters and rules that govern their geometry. This representation allows for a high level of flexibility and adaptability in design, as changes to the parameters will automatically update the associated geometry of the object. For instance, if the dimensions or any attributes of a wall are altered, the entire model reflects those changes in real time without the need for manual adjustments.

This approach enhances collaboration among project stakeholders since the model can be easily modified while maintaining consistency and accuracy across the project. By defining relationships, constraints, and behaviors through parameters, complex systems can be managed efficiently. This representation is fundamental to utilizing BIM effectively, as it taps into the power of computational design to optimize building performance and improve decision-making throughout the lifecycle of a project.
