When should a full section be used?
Full sections This type of section is used for both detail and assembly drawings.
When the cutting plane divides the object into two identical parts, it is not necessary to indicate its location..
What is the use of hatching?
Hatching, also called cross-hatching, technique used by draftsmen, engravers, and other artists who use mediums that do not allow blending (e.g., pen and ink) to indicate shading, modeling, and light and shade.
What is an aligned section view?
An aligned section view / cut is a view created from a cutting profile defined from non parallel planes. In order to include in a section certain angled elements, the cutting plane may be bent so as to pass through those features. The plane and feature are then imagined to be revolved into the original plane.
What is a removed section?
Views, Continued Removed sections A removed section is a section or partial section not directly projected from the view containing the cutting plane and not revolved or turned from its normal orientation.
What are the different types of sectioning?
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 a broken out section view?
A broken-out section is part of an existing drawing view, that is used to remove material to a specified depth in order to expose inner details of a model. A closed profile, usually a spline, defines the broken-out section.
What is a section view?
∎ 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.
Do you show hidden lines 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.
What is half section?
A half section exposes the interior of one half of an object while retaining the exterior of the other half. 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.
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 hidden line?
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. Sometimes they are used to make a drawing easier to understand. Often they are omitted in an isometric view.
What is the purpose of a section view?
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 are the 7 types of section views?
Types of Sectional ViewsFull Section. If the imaginary cutting plane passes through the entire object, splitting the drawn object in two with the interior of the object revealed, this is called a “full section.” A full section is the most widely-used sectional view.Half View. … Offset View. … Revolving View. … Broken View.
What is full section and half section?
Full Section. Replacing the view. Half Section. 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.
What is the difference between a half and full section view?
2What is the difference between a half and a full section? -A full section view is the full section. The half section view is half of the section. It is used when the object is symmetrical in both inside and outside details. One-half of the object is sectioned and the other half is shown as a standard view.
What is section line in drawing?
Section lines are very light. When sketching an object or part that requires a sectional view, they are drawn by eye at an angle of approximately 45 degrees, and are spaced about 1/8” apart. Since they are used to set off a section, they must be drawn with care.
