To begin, establish the necessary structural components such as beams, slabs, and columns based on the CAD drawings of the construction project. The main steps using the Structure function are outlined below:
1) Create Project Template
There are four distinct project template types available—structural, construction, mechanical, and architectural—each tailored for different disciplines and project environments. Selecting the appropriate template ensures that the modeling environment suits the intended profession and project needs.
For example, when working on architectural projects, the architectural template is chosen, which includes elements like doors and windows not present in the structural template. Conversely, the structural template includes components such as foundations and steel bars that are absent in the architectural template. The initial settings, including default view ranges and section displays, differ between templates. Note that architectural doors cannot be drawn within the structural template environment. Therefore, it is crucial to pick the template that corresponds to the model you plan to create.
2) Establish Elevations and Grid Network
Elevations and grids are essential in building models, serving as references for construction and key benchmarks in Revit. When drawing grids, use the Grid tool found in the Reference panel under the Revit Common tab.
Start by drawing a single grid line. To create a series of grids at fixed intervals, utilize Revit’s Array function to replicate the grid lines sequentially. Similarly, use the Elevation tool in the same panel to draw elevation markers following the same method.
3) Arrange Structural Columns
Use the “Column” tool in the Structure module to build your construction model. Begin by switching the view to the first floor. Align the columns according to the grid and the column layout specified in the CAD drawings.
Columns in Revit are parameter-driven; you can insert column families of different shapes and modify their parameters—such as height and length—to fit project requirements.
One of Revit’s key advantages is its ability to reduce modeling errors. For example, when data changes in a schedule table, corresponding changes automatically update the component information across plans, elevations, and sections. This interconnectedness ensures consistency throughout the model.
Parametric modeling is a standout feature: if you modify a parameter of a concrete column, its representation in all views updates accordingly. When loading a rectangular column, select the appropriate family type from the popup, then adjust parameters via the “Edit Type” function in the properties panel.
Because architectural and structural models are created in separate modules by different disciplines, they exist as independent projects with no overlap. To combine them, use Revit’s linking function to integrate architectural and structural models into a single project.
Constructing a structural information model involves building components like elevations, grids, columns, and walls within the structural template environment, while architectural models are built in their respective template environment. Though the methods are similar, each discipline operates within its specialized template.
4) Generate Beams, Slabs, Shear Walls, and More
Structural elements such as beams, slabs, and shear walls are created using parametric modeling techniques. These components are typically placed based on the established grid system, similar to column placement.
This parametric approach helps minimize low-level errors during the modeling process, enhancing accuracy and efficiency.
