A sectional view or a section looks inside an object. Sections are used to clarify the interior construction of a part that cannot be clearly described by hidden lines in exterior views. By taking an imaginary cut through the object and removing a portion, the inside features may be seen more clearly.
What is the purpose of Section drawing?
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. The cut line is called a “cutting plane”, and can be done in several ways.
What are the two purposes of a section drawing?
They are: 1) To show the alternate position of mating parts. 2) To show the relationship of parts that fit together. 4) To illustrate function of object.
What is the main purpose of a building section?
The purpose of a section is to show, graphically, the main volumes of the building and the main building material components. Notes and dimension lines are attached to the section cuts. The key to producing a useful section is to “cut” through the most typical building volumes.
What are the basic principles of sectioning?
Rule 2: The section lines in all areas should be parallel. Section lines shown in opposite directions indicate a different part. Rule 3: All the visible edges behind the cutting plane should be shown.
What are the 7 types of section views?

Why is it important to draw a plan section and elevation?
Architecture. Architectural plans and elevations play a crucial role in the construction process. The plans include schedules, working drawings, elevations, and other significant sheets. They are used by architects and builders to better understand how to go about the construction process.
What is a section plan?
Plan drawings are in fact a type of section, but they cut through the building on a horizontal rather than vertical plane. … The direction of the plane through which the section is cut is often represented on plan drawings and elevations by a line of long and short dashes, called a section plane. Read:
What is direction of sight in sectioning?
To produce a sectional view, a cutting plane is assumed to pass through the part. The cutting plane is then removed, and the two halves are drawn apart, exposing the interior construction. In which case, the direction of sight is towards one half of the object. The other half is then mentally discarded.

This type of section is used for both detail and assembly drawings. When the cutting plane divides the object into two identical parts, it is not necessary to indicate its location.

What is section view explain with examples?
A sectional view or a section looks inside an object. Sections are used to clarify the interior construction of a part that cannot be clearly described by hidden lines in exterior views. By taking an imaginary cut through the object and removing a portion, the inside features may be seen more clearly.
What is difference between full section and half section?
As in all sectional drawings, the cutting plane take precedence over the center line. Here is another example of a half section. Remember that only one fourth of the object is removed with a half section, whereas half of the object is generally removed with a full section.
