What is rear view in drawing?
The back view can also be referred to as the rear view. To produce an accurate drawing of an object, it is seldom necessary to show all six views. A working drawing typically shows three views of an object, which is sufficient to describe its shape and give all the required dimensions.
Which view should be drawn first when creating a multiview drawing?
When choosing the front, or principal, view of an object, select the view you would choose if you could only show the viewer one view to describe the object. In creating the multi-view drawing of the bus, the front, or principal, view was drawn first.
What are the three views in a standard multiview drawing?
Although six different sides can be drawn, usually three views of a drawing give enough information to make a three-dimensional object. These views are known as front view, top view and end view. Other names for these views include plan, elevation and section.
What is the purpose of multi view drawing?
The purpose of a Multiview Drawing is to represent a three dimensional object on a two dimensional sheet of paper or in a two dimensional drawing space.
Why is second and fourth quadrant not used?
Overlapping projection views create confusion in the drawing. Therefore the 2nd angle projection system is not used to draw engineering drawings. Similarly when the object is placed in the 4th quadrant both top and front view will overlap. Therefore fourth angle projection is also not used.
Which one is used to draw projection?
Axonometric: “Axonometric means “to measure along axes”. It is a type of projection used to draw an object when it is rotated along one or more of its axes relative to the plane of projection.” It has three types that are isometric, Dimetric and trimetric….
What is the symbol of first angle projection?
When view are drawn in their relative position Top view comes below Front view, Right side view drawn to the left side of elevation. A First Angle Projection drawing is identified by the first angle projection symbol. The angle of projection symbol typically appears in angle of projection block near to Title block.
Which of the following is true for the first angle projection?
Here 1st angle represents the initial stage in forming projection of planes so 1st quadrant represents 1st angle projection. Explanation: First angle projection is recommended by Bureau of Indian Standards but USA and other countries recommend third angle projection.
Which information is required to draw the perspective?
The information needed to construct a perspective image is the eye level and the vanishing point (or points): The eye level. This is an imaginary line drawn horizontally at the height of a viewer’s eye that establishes the position of the horizon….
Which line is used for visible outlines?
A visible line, or object line is a thick continuous line, used to outline the visible edges or contours of an object.
How many orthographic views are there?
three different
Which view generally contains the least amount of hidden lines?
FRONT
What do the phantom lines in this view represent?
Phantom lines: Phantom lines are used to indicate imaginary features. For example, they are used to indicate the alternate positions of moving parts, and adjacent positions of related parts. The line type is long dash – short dash – short dash and the line weight is usually thin (0.3 mm).
What do hidden lines in orthographic projection?
What do hidden lines in orthographic projections denote? Explanation: Hidden lines denote those parts which cannot be seen when viewing the object. They are used when there are holes or slots in the object if they cannot be viewed directly. Change of plane is indicated by outlines.
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….
How do I find hidden lines in an object?
A drafter—in deciding whether a line in a view should be represented as hidden or as visible—relies on the fact that in third-angle projection the near side of the object is near the adjacent view, but in first-angle projection the near side of the object is remote from the adjacent view.
