What is sectioning in drafting?
Sectional drawings are multi-view technical drawings that contain special views of a part or parts, which reveal interior features. Sectioning uses a technique that is based on passing an imaginary cutting plane through a part. In the figure, views a are Standard multiview projections.
What is a cutting line in drafting?
Cutting plane lines are thick lines that run through the center of the object that the interior wants to provide an interior view of. Two perpendicular lines with arrows showing in which direction the interior of the object should be viewed are drawn at the end of the line.
What are the rules of sectioning?
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.
What is the difference between a half and 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. Half sections or views. In this type of section, only half of the space or object is cut away.
What is the difference between section lines and cutting plane lines?
The section-lined areas are those portions that have been in actual contact with the cutting-plane. Half Section is used toshow the exterior and interior of the part in the same view. The cutting-plane line cuts halfway through the part and removes one quarter of the material.
How do you draw a section line?
You draw a section line by specifying a start point, an endpoint, a length, and a height for the section. You can specify additional points between the start point and the endpoint to create jogs in the section. The section line acts as a cutting plane, slicing a section from the building model.
What is the two types of cutting plane lines?
There are two forms of cutting plane lines approved for engineering drawings. The first form consists of evenly spaced dashes with arrowheads indicating the direction of sight. The second form consists of alternating long dashes and pairs of short dashes.
What are the parts of section?
Types of sections include the introduction or intro, exposition, development, recapitulation, verse, chorus or refrain, conclusion, coda or outro, fadeout, bridge or interlude.
How do you cut a section in CAD?
A full section view is generated by running the cutting plane through the entire length of the object being sectioned.
- Click Layout tab Create View panel Section drop-down Full.
- Click the view you want to use as the parent view.
- Click in the drawing area to indicate the start point of the section line.
What are the types of cutting plane?
Types of Cutting Planes:
- Vertical Section Plane.
- Horizontal Section Plane Cutting plane parallel to horizontal plane.
- Profile Section Plane.
- Auxiliary Section Plane.
- Oblique Section Plane.
What is called section?
a part that is cut off or separated. a distinct part or subdivision of anything, as an object, country, community, class, or the like: the members’ section of a golf course;the left section of a drawer.

What are examples of sections?
An example of a section is a piece of pie. To section is defined as to divide something up into parts. An example of to section is to divide a playing field up into different obstacle courses. (music) A group of instruments or voices in the same class considered as a division of a band, orchestra, or choir.
