Perspective Projection The Perspective projection is the approximate representation on a flat surfaceof the image perceived by the eyes.
To utilize this view to show a surface true sizea view must exist or be drawn where that surface appears as a line. Drawingg of the orthographic projection is of an upside down vehicle: The purpose of engineering drawing is to capture all the geometric features of a product or a component accurately and unambiguously. The isometric projection shows the object from the angles in which the scales along each axis of the object are equal.
D Bhatt Engineering Drawing 50th edition. This projection shows ejgineering the object as it looks from the front, rightleft, top, bottom, or back, and are positioned relative to each other according to the rules of either first-angle or third-angle projection. The Perspective projection is the approximate representation on a flat surfaceof the image perceived by the eyes.

Engineered computer models can also be printed in 3-dimensional form using special 3 D printers. The most characteristic features of drawingg projection are that objects are drawn:.
The other two types of frawing projection are: Once a given view showing the surface as a eidtion is identified. Despite of the fact that auxiliary views are projected onto planes which are inclined to the principal projection planesthey are still classified as orthographic-views. The following example shows the oblique projection of a camera. It can now be produced using computer technology.
It is a form of parallel projectionhere the view direction is orthogonal to the projection plane, resulting in each plane of the scene appearing in affine transformation on viewing surface. However, the terms are becoming an anachronism since most copies of engineering drawings that were made using a chemical-printing process that yielded graphics on blue-colored paper or of blue-lines on have been superseded by more modern reproduction processes that yield black or multi-color lines on the white paper.
Isometric Projection The isometric projection shows the object from the angles in which the scales along each axis of the object are equal.

It is much more common to see partial auxiliary-views that show only TS features. Using the auxiliary view allows for inclined plane to be projected in true size and shape. With this projectionupto six pictures of an object are producedwith each projection plane parallel to one of the co-ordinate axes of object. It is not possible to show an oblique surface in a primary auxiliary view. The views are positioned relative to each other according to either of two schemes – first angle or third angle projection.
Multiview Orthographic Projections With this projectionupto six pictures of an object are producedwith each projection plane parallel to one of the co-ordinate axes of object.
The following example shows the elevation of a slab of wood having the raised panel. The other two types of axonometric projection are:. It is usually created in accordance with standard conventions for layout, nomenclatureinterpretationappearanceetc. The true size and shape of any feature in a technical drawings can only be known when the Line of Sight is perpendicular to the plane which is considered as reference. The auxiliary view is an orthographic view that is projected into any plane other than one of the 6 principal views.
Posted by Ali Raza at Orthographic projection is a way of representing a 3-dimensional object in two dimensions. This plane is either turned down into the horizontal plane or is wheeled into the vertical plane.
Friday, 24 June Different types of projections: Although six hbatt sides can be drawn three sides of a drawing give enough information to make a three-dimensional object. Since most of the other surfaces will be fore-shorteneda complete auxiliary-view becomes more difficult to read. Newer Post Older Post. Thus when reading lines on the object in this view adjacent to a engineerinb viewthe same rules apply to reading lines in adjacent principal-views.
Here in both the oblique-projection and the orthographic-projectionparallel lines of source object produce parallel lines in the projected image. All these views are known as front editionn, top view and right side view. Click here to download full Book Download. The most characteristic features of this projection are that objects are drawn: It is further divided into Multiview Orthographic projections and Axonometric projection.
