Do sectional views show cutting planes?
A sectional view represents the part of an object remaining after a portion is assumed to have been cut and removed
. The exposed cut surface is then indicated by section lines. Hidden features behind the cutting plane are omitted, unless required for dimensioning or for definition of the part.
What does the section view show?
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 do sectional drawings show?
A ‘section drawing’, ‘section’ or ‘sectional drawing’ shows
a view of a structure as though it had been sliced in half or cut along another imaginary plane
.
How do you show a cutting plane?
What line is used to show cutting planes?
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.
How does a cutting plane relate to a section?
Cutting plane lines which show where the cutting plane passes through the object,
represent the edge view of the cutting plane and are drawn in the view(s) adjacent to the section view
. Here the cutting plane is drawn as an edge in the top view, which is adjacent to the sectioned front view.
What is a cutting plane?
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 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 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 are the characteristics of a full section view?
- A section lined area is always completely bounded by a visible outline.
- The section lines in all areas should be parallel. …
- All the visible edges behind the cutting plane should be shown.
- Hidden features should be omitted in all areas of a section view.
Can you dimension a section view?
Dimensioning the interior features would require dimensioning to hidden lines which is poor practiced. The problem is eliminated by creating a sectional view which shows the interior details. Once this view has been created,
you can dimension the interior details in the sectional view to complete the drawing
.
What are the difference between full section and half section views?
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
.
Do you section shafts?
Exceptions to Sections
The following elements
should not be sectioned when the cutting plane passes through them
. Ribs, shafts, bolts, nuts, rivets, rods, keys, pins and similar components.
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 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.
What is the advantage of sectional view?
Section views are used to supplement standard orthographic view drawings in order to completely describe an object. They
improve visualization of designs, clarify multiviews and facilitate dimensioning of drawings
. Hence they are an important aspect of design and documentation.
How do you read a section view in a drawing?
Where and why a cutting plane is drawn in drawing?
Cutting plane lines are used
to show the location of cutting planes for sectional views
. 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.
What views are included in a multiview drawing?
What is sectional front view?
The view obtained after removing the front half portion of an object
is called a Full Sectional Views or Front Sectional Views or Simply Sectional Elevation. When the cutting plane cuts the object lengthwise, full sectional front view is obtained. It is also called longitudinal section.
Is a type of section where the cutting plane is drawn horizontally?
Sectional Top View
:
When an object is cut by a horizontal cutting plane or Auxiliary Inclined Plane, the top view obtained is called the Sectional Top View.
How many cutting planes are used in half sectioning?
Half section: This is generally used for symmetrical objects.
Two cutting planes
at right angles to each other pass halfway through the view up to the centerline. Thus only one quarter is assumed to be removed.
When the cutting plane cut the entire object the section is known as?
What does the area filled with section lines on a section view represent?
Section lined areas represent
materials that have actually been in contact with the cutting plane line
.
Which type of line is used to show the edge view of cutting plane?
CUTTING PLANE LINES
– which show where the cutting plane passes through the object, represent the edge view of the cutting plane and are drawn in the view(s) adjacent to the section view.
What are the types of section plane?
- Vertical Section plane.
- Horizontal Section Plane.
- Profile Section plane.
- Auxiliary Section plane.
- Oblique Section plane.
Do you section webs?
MAE 2000 Section Views 201310When the cutting plane passes flatwise through aweb, rib, gear tooth, or similar flat machineelement, in order to avoid a false impression ofthickness or solidity,
the element should not besectioned
.
What is the purpose of section lining?
Section lining, sometimes referred to as cross-hatching, is used
to indicate material in the sectioned part
. Most often, the general purpose section lining symbol is used to represent any material. The exact type of material used to produce the object is usually given as a note somewhere else in the drawing.
What are section lines used for?
What is a section view in Solidworks?
What does it mean to view a plane of 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
. Removed sections.
What is sectional front view?
How do you read a section view in a drawing?
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.
