Sections are used to show interior details clearly.

The process of sketching the internal configuration of an object by showing it cut apart is known as sectioning.

SECTIONING IN ENGG DRAWING 1. Sections are an essential part of any. The interior features are represented by hidden lines in usual orthographic views which results in confusion and difficulty in understanding the drawing Fig.

A cutting-plane line shows where object was cut to obtain the section view. The following texts are the property of their respective authors and we thank them for giving us the opportunity to share for free to students teachers and users of the Web their texts will used only for illustrative educational and scientific purposes only. Or revolved sections removed sections offset sections and assembly sections.

For buildings this can be useful as it gives a view through the spaces and surrounding structures typically across a vertical plane that can reveal the relationships between the different parts of the buildings that might not be apparent on plan drawings. Cross hatching in the section view shows the solid surface of the object which were cut through to produce the section. The purpose of the A-A cross section is to show the basic shell of the house the structural posts holding up the roof beam the rough opening height of.

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. Sectioning is used frequently on a wide variety of Industrial drawings. A simple bracket is shown in Fig.

In this example blocks A and B result after the block in figure 1 has been Sectioned. Purpose of Sectioning On many occasions the interior of an object is complicated or the component parts of a machine are drawn assembled. A section drawing section or sectional drawing shows a view of a structure as though it had been sliced in half or cut along another imaginary plane.

In order to show such features clearly. In thirdangle projection the sectional view is placed on the side behind the sectioning viewing plane. Section complex assemblies and parts is important to see detail in Engineering Drawing.

The Purpose of Engineering Drawings. Sectioning A sectional view shows the part of the component in front of the cutting plane arrows. A section is used to show the detail of a component or an assembly on a particular plane which is known as the cutting plane.

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. 81 and it is required to draw three sectional views. Thus some methods of sectioning is discussed.

The purpose of showing the hatching lines is to tell the observer as to where exactly the imaginary cutting plane cuts the material of the object as it slicespasses through the object. When you cut an apple in half you have sectioned it. This tutorial will demonstrate how to draw this cross section.

A section drawing is one that shows a vertical cut transecting typically along a primary axis an object or building. An animated video attempting to help beginners understand the purpose for use of and methodology behind section views. The hatching lines differentiate the areas which are cut and those areas which are not cut by the cutting plane.

The drawing below is the resulting A-A cross section. Note that cross sections are also indicated for sections B-B C-C and D-D. Sectional views in engineering technical drawings.

The section reveals simultaneously its interior and exterior profiles the interior space and the material membrane or wall that separates interior from exterior providing a view of. D Z v o Á v P v P v v s Á µ v u v o t l W l ï. A section is used to show the detail of a component or an assembly on a particular plane which is known as the cutting plane.

Material which has been cut by the cutting plane is hatched. However it is possible to infer that the section is and historically has been the most interesting drawing since it is understood as a representation of the architectural design itself.
