Which set of views is used for a horizontal vessel?

• A. Elevation view and end view
• B. Elevation view and plan view
• C. Plan view and section view
• D. Section view and isometric view

Answer: (A)

Think of a horizontal vessel as a long cylinder lying on its side, so its main measurements are length and diameter. The elevation view runs along the length of the vessel, showing how tall it sits and how long it is, while the end view looks straight at one circular end, revealing the true diameter. Together, these two views convey the overall external shape and size without distortion. Other paired views don’t give both the length and the true circular end size in a straightforward, complementary way—for example, a plan view shows the top outline but not the end shape, and a plan with a section or an isometric view adds perspective or internal detail that isn’t needed for communicating the basic geometry of a horizontal vessel.
