Sectioning Sectioning Of Views Plan Elevation And End Views In The technique called section views is a very important aspect of design and documentation. it is used to improve the visualization and clarity of new designs, clarify multiview drawings, reveal interior features of parts, and facilitate the dimensioning of drawings. for mechanical drawings section views are used to reveal interior features of an object when hidden lines cannot properly. It can be created as a circle or freehand line around that area. detailed view reference letter have the same purpose as section reference letters. we are using it as a detail view identifier. every detail view should be marked with a capital letter placed near the viewing line and above the detail. Theory of sectioning: <br ><br >the detail of an object can be shown by drawing a limited number of carefully chosen views and showing external features of the object by firm lines and invisible detail by hidden lines. but when the interior of the object is complicated then the method of showing interior details by hidden lines makes the view confusing and hard to read. in such cases the. A half section is a view of an object showing one half of the view in section, as in figure 19 and 20. figure 19 full and sectioned isometric views. figure 20 front view and half section. the diagonal lines on the section drawing are used to indicate the area that has been theoretically cut. these lines are called section lining or cross.

After reading this chapter, you will be able to. identify sections and sectional views of solids. draw sectional views of cut surfaces of solids such as prisms, pyramids, cylinders and cones. draw the true shape of the cut surfaces of simple solids. locate the position of the cutting plane if the true shape of a section is known.
