What is a revolved section of a plane?
This section in a plane that is perpendicular to the plane of axis, is then revolved and brought in to the plane of the axis and placed in the view in which the axis is seen as a line. This section shown by a thin continuous line is known as revolved section.
What is a section view drawing?
A section view drawing is a drawing produced after the construction of a building to show how it will appear when it is cut in two. These are usually produced on-site by engineers, architects, or builders to help with their plans.
When should a revolved section be used?
Use a revolved section when the part is long and thin and when its shape in cross section is the same throughout, as in Figure 8-14.

What is a removed section view?
So, what is it? The removed section view is a zero-thickness slice through the model showing only cut edges and hatching perpendicular to the cutting line. That's different than the traditional section view, which is projected parallel to the cutting line.
What is the purpose of a section view?
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 a revolved section on a drawing?

A half-section is a view of an object showing one-half of the view in section. Half Section. • Symmetrical parts can be shown in half sections.
Which sectional view is the most common?
If the imaginary cutting plane passes through the entire object, splitting the drawn object in two with the interior of the object revealed, this is called a "full section." A full section is the most widely-used sectional view.
How do you read a section view?
Rule 1: A section lined area is always completely bounded by a visible outline. 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.
Do section views have hidden lines?
Section views do not include hidden lines. Any material cut when a section view is defined is hatched using section lines. There are many different styles of hatching, but the general style is evenly spaced 45° lines.

How does an assembly drawing differ from a detail drawing?
Detail drawings provide detail descriptions of a part for construction or fabrication, whereas assembly drawings emphasis how the part is to be used. Detail drawings are fully dimensioned. Assembly drawings show the parts together in assembly.
What is full section?
Full Section. In a full section, the cutting plane line passes fully through the part. Normally a view is replaced with the full section view.
What are half sections?
A half section exposes the interior of one half of an object while retaining the exterior of the other half. Half sections are used mainly for symmetric objects or assembly drawings. A centerline is used to separate the two halves. Hidden lines should not be shown on either half.
Revolved Sections In Technical Drawings
Revolved sections are technical drawings that are frequently used to show the cross-sectional shapes of long parts. To make revolved sections to show the cross-section, draw the cross-section on the part which is revolved case of the cross-section to show to the reader.
Removed Sections In Technical Drawings
The removed section technique is a very useful technique to show the important details of a complex part on the technical drawing sheets. To create a removed section from a part, you need to show the section as section A-A, section B-B, etc. on the main part. Then show the section cut view on the other part of the sheet to show additional details.
Offset Sections In Technical Drawings
While you are creating a section view of a part, you can realize that it is not sufficient to show all the necessary details with a straight section line. In this case, you can use the offset section line which includes all the required internal details that must be shown on the technical drawing.
Conclusion
Use of the revolved, removed, and offset sectionings in technical drawings is very simple and useful like above.
How does a revolved section show the shape of an object?
A revolved section shows the shape of an object by rotating a section 90 degrees to face the viewer. The three revolved sections illustrated in the spear-like object of figure 12 show the changes that take place in its shape.
When is it possible to section an object?
It is possible to section an object whenever a closer look intentionally is desired. Here is an object sectioned from two different directions.
What is a hidden line in a sectional drawing?
Hidden lines are usually not shown on the un-sectioned half unless they are needed for clearness or for dimensioning purposes. As in all sectional drawings, the cutting plane take precedence over the center line. Here is another example of a half section.
What is the process of sketching the internal configuration of an object by showing it cut apart?
The process of sketching the internal configuration of an object by showing it cut apart is known as sectioning. Sectioning is used frequently on a wide variety of Industrial drawings.
What is offset section?
An offset section is a means of including in a single section several features of an object that are not in a straight line. To do this, the cutting plane line is bent, or “OFFSET” to pass through the features of the part.
How far apart are section lines?
When sketching an object or part that requires a sectional view, they are drawn by eye at an angle of approximately 45 degrees, and are spaced about 1/8” apart. Since they are used to set off a section, they must be drawn with care.
What is section lining?
Section Lining. The lines in the figure above, which look like saw marks, are called section lining. They are found on most sectional views, and indicate the surface which has been exposed by the cutting plane. Notice that the square hole in the object has no section lining, since it was not changed by sectioning.
What is a revolved section?
Revolved section. When a drawing has may numbers of long structural members of different cross sections, it is very difficult to identify the cross section of the member. In a particular view, a rectangular and circular duct may look alike. In such cases, the cross section of each member is shown by revolved section.
What is a half sectional view?
The one quarter portion of the object is assumed to be removed showing only half of the object’s inner details. The projected view is a half sectional view.
How to differentiate section from object outline?
A section is differentiated from the object outline by hatching the sectioned portion by thin continuous lines drawn inclined at 45º to the axis or to the main outline. They should be placed equally, spacing varying from 1.5 to 3.5 mm. In computer aided drawing, many types of default section lines are available.
What is offset section?
In order to obtain more details of the object, the cutting plane may be assumed to be offset as shown in the figure. The section thus obtained is known as Offset section. The position of the offset cutting plane is always shown by a cutting plane line in the view in which it is seen edgewise.
What is the section of an object that is taken through an object at an angle other than 90°?
In a mechanical drawing, a section taken through an object at an angle (other than 90°) to its longest axis is known as Oblique section . The section in the Oblique projection is termed as oblique section as shown in the figure.
How is the cross section of an object formed?
In such cases, the cross section of each member is shown by revolved section. A section is formed by passing a cutting plane at right angle to the axis of the object. This will be the actual cross section of the object. This section in a plane that is perpendicular to the plane of axis, is then revolved and brought in to the plane ...
What is a revolving section?
With this type of section, a space or detail is shown with a cutting plane at an angle, and then the section is rotated so that the cutting plane faces the viewer.
What is section view?
A section view provides architects and contractors another way of understanding how a construction will stand up, as it reveals details of the construction of walls and the thickness and height of beams and other supports. While a floor plan allows for a view of how the walls stand in relation to each other, a section shows where the wall meets the floor, and the distance that separates one floor from another.
What is a full section?
This is the most common section (called a full section) with the imaginary laser cutting a line across the entire construction, offering a view of a portion of the building with the rest of it put to one side.
What is broken out section?
Broken out sections or broken views. With these drawings, only a small portion of the object or space is shown in section. Instead of a section line, the portion that is shown in section is indicated by an irregular cut line.
What is a half section in a drawing?
Half sections or views. In this type of section, only half of the space or object is cut away. This allows you to see part of it in elevation, while the other part of the drawing gives a glimpse inside.
