What happens to the quantities associated with a building if a wall is stretched in a parametric BIM?

When a wall is stretched in a parametric BIM, the quantities associated with the building will adjust automatically based on that change. This capability is inherent in parametric modeling, where dimensions and relationships between elements are linked. When one element changes, such as a wall being elongated, the software recalculates the related quantities, including length, area, and potentially volume, to reflect the new dimensions.

This functionality allows for more accurate and efficient project management, as it ensures that the data associated with the building model remains current, eliminating the need for manual updates. Therefore, the quantities will change based on the adjustments made to the geometry of the model. This adaptability is one of the key benefits of using parametric BIM in construction management, allowing for dynamic interactions and real-time data updates throughout the project's lifecycle.
