In Revit, what is often the first step in creating a building with multiple levels?

Setting up the building levels is a fundamental step in the design process within Revit when creating a building with multiple levels. This step involves defining the various floor levels that the building will have, which is crucial because these levels serve as the basis for all subsequent design elements, including floor plans, walls, and other building components. Establishing the levels first ensures that the architectural model is organized correctly and allows for accurate dimensional relationships between different floors.

Once the levels are set, you can proceed to draft the floor plans, as each level will dictate where these plans are drawn relative to the overall structure. The creation of a 3D model and the application of structural elements come afterward, utilizing the defined levels to ensure that the model accurately reflects the intended design. This approach aligns with the parametric nature of Revit, where elements are linked to these defined levels, allowing for automatic updates and coordination throughout the project.
