What Is Sectioning In Engineering Drawing

A section is an imaginary cut taken through an object to reveal the shape or interior construction.

What is sectioning in engineering drawing. This indicator will then generate a section view. Figure 20 front view and half section. A section view is a view used on a drawing to show an area or hidden part of an object by cutting away or removing some of that object.

Sectioning is used frequently on a wide variety of industrial drawings. Sections are provided to give a clearer and more detailed drawing to show what the design is and what is required to complete the project. Sectional views in engineering technical drawings.

Cross hatching in the section view shows the solid surface of the object which were cut through to produce the section. The diagonal lines on the section drawing are used to indicate the area that has been theoretically cut. There are objects that may have internal features holes grooves etc.

These details can only be shown with a sectioning view. In this example blocks a and b result after the block in figure 1 has been sectioned. Sections are used to show interior details clearly.

Figure 19 full and sectioned isometric views. These lines are called section lining or cross. The cut line is called a cutting plane and can be done in several ways.

See this and over 140 engineering technology simulation videos at http. A section is a view of no thickness and shows the outline of the object at the cutting plane. The process of sketching the internal configuration of an object by showing it cut apart is known as sectioning.
