What are the four main views of working drawings?

The four main views of working drawings are indeed plan, elevation, sectional, and detailed.

A plan view provides a top-down representation of the building or object, allowing one to see the layout and arrangement of spaces and structures. Elevation views present the vertical aspects of a design, showcasing the exterior appearance and height relationships. Sectional views are crucial for understanding how different parts of a structure interact internally, highlighting the internal components and their relationships in a cut-through representation. Detailed views, on the other hand, focus on specific elements within a drawing, giving a more comprehensive understanding of complex components or assembly details that might not be evident in broader views.

These four types of views work together to provide comprehensive information necessary for construction and understanding the design, making them essential in the field of architectural drawing and planning.
