Three-View, Plan View and Elevation View Drawings
CHAPTER Three- view , Plan view and Elevation view Drawings Technical Drawings are the language engineers and architects use to communicate their ideas and designs to journeymen. It is a language based on lines and s:m- bols that have specific meanings. Journeymen must possess the sldll to interpret these symbols and lies, so that they may install and maintain piping systems. This chapter discusses the use of three- view draw- ings, section Drawings , and schematic Drawings , and introduces some special-purpose Drawings , such as ex- ploded Drawings and wiring diagrams. The photograph in Fig. 2-1 clearly depicts the over-all appearance of a concrete block. A three- view drawing will most clearly show the appearance as well as the exact size and other details of construction of an object. The three- view drawing of the concrete block shown in Fig. 2-2 is a drawing with the Top view posi- tioned directly above the Front view and the Right- Side or Left-Side view positioned directly to the right or left of the Front view .
The elevation view is the view from one side of the object. Fig. 2-21 is an example of this type of drawing, showing the plan view, four elevation views and the bottom view. Each one of these views shows two of the principle dimensions and can show only two. The front view or front elevation shows the width and height of the front of the object.
