What is the primary use of 'Levels' in Revit?

The primary use of 'Levels' in Revit is to define vertical heights within a model. Levels serve as reference planes that establish the elevation points for different elements in the architectural design, such as floors, roofs, and beams. This vertical organization helps ensure that all components of the building are accurately placed relative to each other, maintaining a coherent and well-structured model.

Using levels effectively allows designers to manage the vertical dimensions of their projects, enabling them to create multi-story buildings and establish relationships between various design elements. By defining the heights at which certain features are located, it becomes easier to perform coordination tasks and achieve the desired architectural outcomes.
