Half sections are commonly used to show both the internal and outside view of symmetrical objects. A single view of an object is rarely adequate to show all necessary features. A cutting plane line shows where object was cut to obtain the section view.

No need for additional orthographic views. Broken View Removes sections from large objects between two points and moves the remaining sections close together. REVOLVED SECTION VIEW Revolved sections show cross-sectional features of a part.

A full section is the most widely-used sectional view. A cutting plane does not necessarily need to cut the whole object. A revolving view is effective for elongated objects or.

There is no cutting plane line. However the terms are becoming an anachronism since most copies of engineering drawings that were made using a chemical-printing process that yielded graphics on blue-coloured paper. Figure 20 - Front view and half section.

Break line is a thin continuous line and is drawn freehand. Types of Section in Engineering Drawing. Section lines are used to define areas that represent where solid material has been cut in a sectional view.
