- Theory of Sectioning:
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 object is assumed to be cut by an imaginary plane from a particular section. The part of the object in between the observer and the cutting plane is removed to expose the hidden detail of the object. The cut surfaces are identified by drawing section lines and the view thus obtained is called the “Sectional View” or “View in Section” of the remaining object.
Purpose of Sectioning:
To clarify the internal detail of the object by reducing or eliminating the hidden lines from the view.
Full Section Definition:
When the cutting plane passes entirely through the object, in a straight line the view obtained is called full section of the object. If the object is symmetric then this method will divide the object into two identical parts.
Half Section Definition:
In symmetrical objects, to show the interior and exterior details in the same view, half sections are drawn. Two cutting planes (90O to each other) are used to cut the object from two center lines to remove quarter portion of the object.

I like it very much how it was explained everything. Thank you.
Thanks dear! You are welcome
Very much good drawing with a very clear and described information. Thanks for your time. It helped me to understand the sectional cutting of a symmetric object
You are welcome dear
I have a question draw full sectional front view and full sectional side view
In this question we have to draw side view and front view . So we have to make it directly or first we have to make front view then top view then side view 👇👇👇
If only two views are asked in the question then no need of top view, you can draw direct also.
amazing! please what kind of paper are you using? paper with small points i mean?
Thanks dear. These are called grid sheets.
It is compulsory to show projections lines
Yes
@@KSGEngineering with which pencil grade should we made
@@TS-mn7yl HB grade is used for object lines that is continuous thick lines, H grade for medium lines and 2H is used for continuous thin lines like projectors
Sir what will be 3rd view as we are advised to make three views of this

I will send you the answer
@@KSGEngineering i have sent you the email.
@@obsessedwithnature6747 check your mail
@KSGEngineering Thankyou so much, sir. I have received drawings.
Kindly check your mail sir
@@obsessedwithnature6747 you are welcome. I have replied to your mail
Thanks
Welcome
Nice
Thanks
Why you didn't draw it in between 4 quadrants
I have drawn it in first angle of projection. You can draw it in third angle of projection as well.
@KSGEngineering by making 4 quadrants, like by dividing, we draw then these drawings...But why you didn't draw it by making sections..plz confirm this
It is not necessary to show 4 quadrants. We just choose a quadrant in which we want to draw our drawing and then we represent that quadrant only. Moreover, drawings can be drawn in only 2 quadrants that is first and third.
@@KSGEngineering but in orthographic projection, we have to draw three views top side and front...but there are only two.
It purely depends upon the question asked in exam. If question says that draw full section front view and top view of a given component, then there is no need to draw front view separately or any other view.

Thanks. Absolutely
