Which view will always be shown in a multiview drawing?
The views projected onto the three planes are shown together in Figure 8.11. The top view is always positioned above and aligned with the front view, and the right side view is always positioned to the right of and aligned with the front view, as shown in the figure.
What are the three principal views of orthographic 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 are different types of projections?
This group of map projections can be classified into three types: Gnomonic projection, Stereographic projection and Orthographic projection.
- Gnomonic projection. The Gnomonic projection has its origin of light at the center of the globe.
- Stereographic projection.
- Orthographic projection.
What are the 4 basic components of an engineering drawing?
The main purpose of engineering drawings is to communicate to other engineers, machinists, etc….Dimensions have four basic components:
- Dimension Text.
- Dimension Line andArrows.
- Extension Lines.
- Gap.
What is meant by orthographic projection?
Orthographic projection, common method of representing three-dimensional objects, usually by three two-dimensional drawings in each of which the object is viewed along parallel lines that are perpendicular to the plane of the drawing.
What is called when two dimensional view of an object as seen from the top bottom front back left or right?
Elevation is the view of a 3-dimensional object from the position of a vertical plane beside an object. In other words, an elevation is a side view as viewed from the front, back, left or right (and referred to as a front elevation, [left/ right] side elevation, and a rear elevation).
What are the three principal views of an object?
Views are normally selected so that most of the features will be visible in the three principal views. The front, top, and left or right side views are most commonly drawn. Many objects are quite complex, and the three principal views may not best present the geometry of the part.
Why are three views used to show the object?
Complex designs require a three view orthographic drawing. Show the object as it would appear to a person looking directly at the object. They are commonly used to communicate designs to people who do not understand or use orthographic drawings. The most common type of pictorial drawing used.
What are the 3 views of isometric drawing?
As a rule, they show an object from three different views (Usually the Front, Top, & Right Side). Each of the views are drawn in 2-D (two dimensional) , and have dimensions labeling the length, width, and height of the object.
What is meant by isometric view?
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.
What are the three axes of isometric drawing?
In isometric drawings, all three dimensions are represented on paper. The three dimensions are represented as three axes: one vertical axis and two horizontal axes.
