In traditional architectural structural design, the limitations of design software often result in a heavy workload when creating structural construction drawings. Structural designers typically spend significant time and effort producing these detailed drawings.
Parametric design, a core feature of BIM technology, has largely addressed this challenge. BIM models use parameterized 3D solid models along with the embedded information within these models to provide detailed descriptions of each structural unit. This integrates 2D elements such as points, lines, and surfaces into specific 3D structural components like beams and columns.
Within BIM technology, the concept of a “family” encompasses most structural components commonly used in 2D design that share repetitive properties. Each family includes not only the geometric information of the components but also extensive non-geometric data such as material properties and logical relationships. Moreover, the parameter information within a family captures all component features and the simple or complex interactions between them. This ensures that the digital component models accurately correspond to their real-world structural counterparts.
All data related to structural components is stored parametrically in BIM’s robust database. By utilizing this data and selecting suitable graphic software, a comprehensive 3D structural model is created. Relationships between components are also represented through parameters in the BIM database.
The powerful parameter modification capabilities of the BIM engine allow users to update data across the database simultaneously when changes are made to structural designs, annotations, symbols, and more. These updates are quickly and accurately reflected in the BIM model. Additionally, any linked components automatically update their parameter data in response to changes, maintaining coordination and consistency throughout the model.
In simple terms, this means that modifying any component in the model will automatically update all associated components, eliminating the need for manual adjustments as was necessary in traditional 2D workflows. This linkage greatly reduces the workload involved in revisions, enhancing both efficiency and design quality.
