On which type of plan are cutting planes for section views typically indicated?

The cutting planes for section views are typically indicated on a floor plan. A floor plan provides a horizontal view of the layout of a building, showing walls, doors, windows, and sometimes additional details like furniture or fixtures. It serves as a key reference point for defining where sections are taken.

In architectural and engineering drawings, the location of the cutting plane is clearly marked on the floor plan to indicate the view that will be shown in the section. This allows anyone reviewing the plans to understand how the building is organized in three dimensions based on the two-dimensional representations on the floor plan.

While other types of plans, such as plot plans, serve different purposes, they do not typically indicate cutting planes for section views as they focus on the overall site layout and external features rather than the details of interior spaces.
