What Is Projection In Engineering Drawing Methods of projection In engineering drawing following four methods of projection are commonly used they are 1 Orthographic projection 2 Isometric projection 31 Oblique projection 41 Perspective projection In the above methods 2 3 and 4 represent the object by a pictorial view 3 8Yes see it In these mgthods of projectiqn a
In other words equal distances do not appear equal on a perspective drawing Thus since engineering and technology depend on exact size and shape descriptions for design the best approach is to use the parallel projection technique orthographic projection to create multi view drawings where each view shows only two of the three dimensions An engineering drawing is a type of technical drawing that is used to convey information about an object from the three dimensional source object with the drawing surface projection plan In both oblique projection and orthographic projection parallel lines of the source object produce parallel lines in the projected image

In order to communicate design intent the mechanical design engineer needs to represent the 3D object in a clear and unambiguous way In Introduction to the Engineering drawings we showed you the building blocks of the engineering drawing As we move throughout the list explaining them in greater depth in this article we will talk about the projection methods used on the engineering drawing Engineering Working Drawings Basics Engineering graphics is an effective way of communicating technical ideas and it is an essential tool in engineering design where most of the design process is graphically based Engineering graphics is used in the design process for visualization communication and documentation
What is a projection in a mechanical engineering drawing The purpose of engineering drawings whether freehand sketching or computer aided design CAD is to represent a physical object or a visual representation of an object so that it can be communicated to others In an engineering drawing a projection is a geometrically represented image So when the two projections are drawn in correct relationship with each other XY repre sents both the HP and VP The views of an object are projected on the respective planes generally by means of two methods for drawing projections that is first angle and third angle methods 4 4 5 Types of Orthographic Projections Based on the

Various types of projections in engineering drawings 3 D projections are useful for generating an image similar to what the designer can produce in their mind However the object is frequently distorted and detail is absent from 3 D projection images In a typical 3D image the viewing angle often doesn t show all of an object s details This document discusses different types of projections used in engineering drawings It describes parallel projections where lines never intersect and perspective projections where lines converge at a point The main types of projections discussed are Orthographic projections where lines are perpendicular to the view plane
