Cutting plane lines are used to indicate where the section or cut is made. Arrowheads on a cutting plane line indicate the direction of sight.
What do the arrows in a cutting plane line indicate?
Cutting plane lines are used to indicate where the section or cut is made. Arrowheads on a cutting plane line indicate the direction of sight.
What type of line separates the two halves of a half section?
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.
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.What type of cutting plane line is indicated?
Cutting Plane Line: In an isometric view, a sectional plane (Cutting plane) line is indicated by Phantom Line.
Which lines are used to show the visible edges of an object?
A visible line, or object line is a thick continuous line, used to outline the visible edges or contours of an object. A hidden line, also known as a hidden object line is a medium weight line, made of short dashes about 1/8” long with 1/16”gaps, to show edges, surfaces and corners which cannot be seen.
How is a cutting plane represented?
A cutting plane is represented on a drawing by a cutting plane line. This is a heavy long-short-short-long kind of line terminated with arrows. The arrows in show the direction of view. Once again, here is an graphic example of a cutting plane line and the section that develops from it.
What is the function of cutting plane line Mcq?
Explanation: Section plane or cutting plane is an imaginary plane which is used to cut the object to visualize the geometry which is hidden inside the object and interpret it which plays an important role in designing many machine parts.Are the arrows at the end of a cutting plane line pointing to the part of the object that is being removed or viewed?
Arrows are placed at the ends of the cutting plane line to indicate the direction of sight. The arrows point to the portion of the object that is kept. Cutting plane lines are thick (0.6 to 0.8 mm) and take precedence over centerlines.
What do section lines indicate?Section Lines: Used to indicate where the cutting plane cuts the material. Section lines are thin and the symbols (type of lines) are chosen according to the material of the object. Section lines are generally drawn at a 45° angle.
Article first time published onWhen the cutting plane cut the entire object the section is known as?
Explanation: When the cutting plane cuts the entire object the section is known as a full section. This method of sectioning is mostly used in sectioning work. It gives the total object details in one section.
Which line is used to show the position of cutting plane in object?
Section lines are used to show areas that have been cut by the cutting plane. Section lines are grouped in parallel line patterns and usually drawn at a 45o angle. The line type is usually continuous and the line weight is thin (0.3 mm).
What is the two type of cutting plane line?
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 is the difference between the section line and the centerline?
Centre lines are drawn to indicate the exact centre of a component being drawn. They are made from a series of lighter long and short dashes. Section lines are special lines placed on a drawing which indicate the area of the drawing through which an imaginary cut has been made to reveal internal details.
When should a leader line end in an arrow?
This can be a dot if the line ends within the outline of the part, an arrow if the line touches the outline or centre line of a feature or without either an arrowhead or a dot if the line touches a dimension. Examples of leader lines with arrowheads and dots are shown in the vice assembly and the movable jaw drawings.
What type of view is created by cutting a parent view about cutting line?
You create a section view in a drawing by cutting the parent view with a cutting, or section line. The section view can be a straight cut section or an offset section defined by a stepped section line.
Which of the following lines are used to show that the object is cut and then viewed?
Which of the following lines are used to show that the object is cut and then viewed? Explanation: Hatching lines are used to show that the orthographic view is drawn after a section of the object is cut. They indicate that the object is cut and it shows the remaining solid body.
What is cutting plane or section?
Cutting planes are used to create section views. The Cutting Plane command draws a cutting plane line on the part view you want to use as the basis for the section view. … You can draw the cutting plane on any part view. This can be any orthographic, auxiliary, or detail view on the drawing.
Why does alphabet of lines are important?
Why is it important to recognize the alphabet of lines? The lines in the Alphabet of Lines are used to describe shape, size, hidden surfaces, interior detail, and alternate positions of parts. Each conveys a particular meaning on the drawing.
What do you call a medium line used to show edges and contours visible to the eye?
Visible line – A medium line used to show edges and contours not visible to the eye. Invisible line – A medium line used to show edges and contours not visible to the eye.
What are the 7 types of section views?
There are a number of different types of sectional views that can be drawn. A few of the more common ones are: full sections, half sections, broken sections, rotated or revolved sections, removed sections, offset sections, and assembly sections.
Are hidden lines shown in a section view?
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.
When the surface is cut by a series of cutting planes the cut surface is called a?
When the surface is cut by a series of cutting planes, the cut surfaces is called a zone.
What is a section view 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.
What is a section plane?
Definition of section plane 1 : a surface seen in section (as in cross section) 2 : a hypothetical plane cutting a section.
What is half section view?
A half-section is a view of an object showing one-half of the view in section, as in the drawing below. The diagonal lines on the section drawing are used to indicate the area that has been theoretically cut. … The lines are thin and are usually drawn at a 45-degree angle to the major outline of the object.
When the solid is cut by a plane inclined to its base then it is known as?
Explanation: When a pyramid or a cone is cut by a plane parallel to its base, thus removing the top portion, the remaining portion is called its frustum. When a solid is cut by a plane inclined to the base it is said to be truncated.
When the solid is cut by a plane parallel to its base then it is known as?
(7) Frustum of Solid: When a Pyramid or a Cone is cut by a Plane parallel to its base, thus removing the top portion, the remaining lower portion is called its frustum.
Which of the following represent reducing scale?
3. Which of the following scales is a reducing scale? Explanation: The representative fraction 1:3 indicates that the dimension of the drawing is one-third of the actual object. Since the drawing is smaller than the actual object, this type of scale is called a reducing scale.
What is a section cut?
‘ In reference to architectural drawing, the term section typically describes a cut through the body of a building, perpendicular to the horizon line. A section drawing is one that shows a vertical cut transecting, typically along a primary axis, an object or building.
How do you draw a half section view?

- 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. …
- Click in the drawing area to indicate end point of the first segment of the section line.
