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 is cutting plane line in engineering drawing?
CUTTING PLANE LINES are used to indicate a plane or planes in which a sectional view is taken. Section views are used to give a clearer view of the interior or hidden feature of an object that normally cannot be clearly observed in conventional outside views.
What is the two types 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 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 the cutting plane line passes through an object?
The sectional view obtained by passing the cutting plane fully through the object is called a full section. The arrows at the end of the cutting plane line indicate the direction of sight for the sectional view. The cutting plane line may be omitted if the view is in orthographic position.
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.
How cutting planes are 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 type of line is used to draw cutting planes?
Dimension lines are drawn using continuous thin (narrow) lines (straight or curved). The given type of line in question is used to represent cutting planes.
What is short break line?
Short break lines are thick, wavy solid lines that are drawn freehand. When either of these break lines is used to shorten an object, you can assume that the section removed from the part is identical to the portions shown on either side of the break. (thin and long with a zigzag) (thick and short, wavy freehand).
How many types of lines are there in engineering drawing?
10 Different Types of Lines Used In Engineering Drawing. For general engineering drawings, the types of lines recommended by the Bureau of Indian Standards shown in table 2 must be used. The thickness of the lines must be chosen according to the type and size of the drawing from any of the six groups given in Table 1.
How many types of scales are there in engineering drawing?
The scales are classified into four categories: Plain Scale. Diagonal Scale. Vernier Scale. Scale of chords.
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.
What is called cutting plane?
In mathematical optimization, the cutting-plane method is any of a variety of optimization methods that iteratively refine a feasible set or objective function by means of linear inequalities, termed cuts. Finding such an inequality is the separation problem, and such an inequality is a cut.
What is section line in drawing?
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. These lines are drawn at full density and should be drawn at certain dimensions.
What is the cutting plane line used for and how does it look?
Half Section is used to 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. The line that separates the different types (interior and exterior) may be a centerline or a visible line.
What is viewing plane line?
viewing plane line. The line used to define an auxiliary view. If the line were projected through the drawing sheet to create a plane, this plane would define the view. The viewing plane line is displayed on the drawing sheet to show the orientation of the auxiliary view in relation to the principal view.
What is removed section?
The removed section view is a zero-thickness slice through the model showing only cut edges and hatching perpendicular to the cutting line. It’s easy, just select two opposed model edges and a view is created perpendicular to the section line, eliminating the need to create any additional construction geometry.
How many cutting plane lines are there?
In the field of engineering, two forms of cutting plane lines have been approved for use on plans. A series of evenly spaced dashes with arrows at the end comprises the first approved form. In the second form, pairs of long dashes are alternated with short dashes to form a cutting plane line.
When an object is cut by a section plane?
When an object is cut by a section plane, parallel to H.P. and perpendicular to V.P., then the sectional view of the object is obtained in top view. For ex – Frustum , which is initially a cone , but it is cut by a section plane, parallel to H.P. and perpendicular to V.P. , top view is obtained.
When a pyramid or cone is cut by a plane?
So there exists 2 x number of sides of base of edges in a pyramid. 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.
What are the thin lines used to indicate where the cutting plane line has cut through material?
Section Line Section lines are used to show the cut surfaces of an object in section views. They are fine, dark lines. Various types of section lines may indicate the type of material cut by the cutting plane line.
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 are 5 types of lines?
There are 5 main types of lines in art: vertical lines, horizontal lines, diagonal lines, zigzag lines, and curved lines.
