In the construction industry, especially in design, the term “parameterization” is commonly used. Parameterization technology is a form of digital information technology applied in design. Since the emergence of Building Information Modeling (BIM), parameterization technology—a sophisticated information technology—has quickly integrated with BIM. Together, BIM and parameterization technology have become a driving force in the construction sector.
Modern architecture increasingly features buildings with complex functions and unique shapes. With advances in information and construction technologies, project owners often demand advanced functionalities, innovative designs, shorter construction times, and reduced costs. To address these requirements, BIM parameterization technology has become the preferred approach.
Parameterization encompasses the entire process of parametric design—from functional analysis to creating and applying parametric models. The core challenge is to develop a model that fulfills design criteria. In parametric applications, the following factors must be carefully considered:
(1) Analyze the basic elements composing the geometric shapes of components, as well as the relationships between those elements.
(2) Identify which elements link to free parameters, ensuring that only these parameters vary freely.
(3) Define the primary features of the model alongside all supporting features.
(4) Use an expression editor to evaluate formulas based on the free parameters.
(5) Establish the sequence of feature creation and proceed with building the model accordingly.
(6) Adjust the values of various free parameters to verify that model changes behave as expected.
In essence, BIM parameterization technology treats the factors influencing building design as parameters. It identifies connections among these factors and organizes them through computer programming to generate a parametric model. These parameters include multiple influencing factors: some are variable parametric variables, while others remain fixed. By modifying the variable parameters, different outcomes can be achieved. This means parametric models are both flexible and controllable, offering significant adaptability in architectural design.
