What is the purpose of the cutting plane line?
Engineers use cutting plane lines on the plans they are drawing up to differentiate what is inside an object and what lies outside it. The cutting plane line bisects the object and provides a view of its interior features.
Why do we cut plane lines in sectional view?
Broken Out Sections In many cases only a small part of a view needs to be sectioned in order to show some internal detail. In the figure below, the broken out section is removed by a freehand break line. A cutting plane line does not need to be shown, since the location of the cut is obvious.
When and why is a section view necessary?
In which case, the direction of sight is towards one half of the object. The other half is then mentally discarded. Drafters use sectional views to improve the clarity of complex objects when internal surfaces result in too many hidden lines. Special conventions are used to make a sectional view easy to understand.
What is a section plane or a cutting plane?
The cutting plane (also called the section plane) is the plane that cuts through a component to create a sectional view showing the internal details that cannot be seen from the outside. It’s like cutting an apple in half.
What symbol is used to indicate the plane where you cut an object?
The cutting plane appears edgewise as a thick dashed line called the cutting-plane line. The arrows at the ends of the cutting-plane line indicate the direction of sight for the sectional view.
What are the lines in a section view used to show where the material is cut called?
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 7 types of section views?
6 Types of sectional views
- Full sections.
- Half sections or views.
- Offset sections or views.
- Broken out sections or broken views.
- Revolving sections or view.
- Removed sections.
What does section view mean?
∎ 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.
Which dimension is common in top view and right side view?
The height dimension is common to the front and side views. The depth dimension is common to the top and side views. 8.21 The arrangement of views may vary as long as the dimension alignment is correct. 8.22A Third angle projection is the standard projection for the United States and Canada.
What is profile view in engineering drawing?
This plane is vertical in position, and may be used as a plane of projection. A projection on the profile plane is called a profile view, or end view, or sometimes edge view, and is often required in machine or other drawing when the plan and elevation do not sufficiently give the shape and dimensions.
Which among the view can convey the true shape of an object on the drawing?
Orthographic projection yields the true size and shape of every such surface in the front, the top, or the side view. A surface parallel to H or V or R, the three principal planes, is perpendicular to the other two.
What is a side view?
1 : a view from the side : a view apart from the main view. 2 : a view of a person or object presenting a side instead of a front toward the observer or camera : a profile view.
What is a top view?
What you see when you look at something from directly above.
How do you convert 2d to isometric view?
Now make sure ortho mode is turned on from the status bar, if it is not turned on then press F8 to turn it on. You can now select isometric plane for your drawing by pressing the F5 key. The three Isoplanes available for selection are Isoplane top, right and left.
What does isometric view mean?
Isometric projection is a method for visually representing three-dimensional objects in two dimensions in technical and engineering drawings. It is an axonometric projection in which the three coordinate axes appear equally foreshortened and the angle between any two of them is 120 degrees.
Why is 30 degrees isometric?
The reason to draw at 30 degree is because at 30 degree all the three axis vary in the same proportion. That is why the figure looks perfect. All the three planes( ie X, Y and Z) are equally inclined to each other at an angle of 120 degrees to each other(ie 360/3=120).
