It is meant for communicating his/her ideas, thoughts and designs to others. A drawing drawn by an engineer, having engineering knowledge, for the engineering purpose is an engineering drawing (or instrument drawing) .  \nApplications of Engineering Drawing  \nEngineering drawing is an essential part of almost all engineering projects. Some important uses of engineering drawing are mentioned below:  \n1. It is used in ships for navigation.  \n2. For manufacturing of machines, automobiles etc.  \n3. For construction of buildings, roads, bridges, dams, electrical and telecommunication structures etc.  \n4. For manufacturing of electric appliances like TV, phone, computers etc.  \nVarious Software’s used for drafting  \nAuto CAD, ANSYS, PRO/E, Ideas, Unigraphics and hyper mesh etc.  \nSCALES  \nThe proportion by which we either reduce or increase the actual size of the object on a drawing is known as scale. It is not possible always to make drawings of an object to its actual size asthe extent of drawing paper is limited and also sometimes the objects are too small to make it clearly understandable by drawing its actual size in drawing paper. Scale is the technique by which one can represent an object comfortably as well as precisely within the extent of drawing paper.  \nIn other words, a scale is a measuring stick, graduated with different divisions to represent the corresponding actual distance according to some proportion. Numerically scales indicate the relation between the dimensions on drawing and actual dimensions of the objects.  \nUses of scale  \n􀀹 To prepare reduced or enlarged size drawings.  \n􀀹 To set off dimensions.  \n􀀹 To measure distances directly.  \nSizes of Scales  \n􀀹 Full size scale  \n􀀹 Reducing scale  \n􀀹 Enlargingscale  \nFull Size Scale  \nThe scale in which the actual measurements ofthe object are drawn to the same size on the drawing is known as full size scale. It is represented as 1:1 scale. If possible, drawing should be done in full scale.  \nReducing Scale  \nThe scale in which the actual measurements ofthe object are reduced to some proportion is known as reducing scale. The standard formats of reducing proportions are:  \n1:2-drawing made to one-half of the actual size  \n1:5-drawing made to one-fifth of the actual size  \n1:10-drawing made to one-tenth ofthe actual size  \n1:50 - drawing made to one-fiftieth of the actual size  \n1:100-drawing made to one-hundredth ofthe actual size  \nEnlarging Scale  \nThe scale in w","cbCaidDtNMbAjNo4","https://ap.wps.com/l/cbCaidDtNMbAjNo4","pdf",4574119,3,1,59,"English","en",105,"# Unit –I\n## Introduction to Engineering Drawing\n## Important Points / Definitions\n## Applications of Engineering Drawing\n## Various Software’s used for Drafting\n## Scales\n## Uses, Sizes, and Classification of Scales\n## Plain Scales\n## Diagonal Scales and Construction Information","[{\"question\":\"What is the purpose of Engineering Graphics in this course?\",\"answer\":\"The course focuses on developing visualization ability through technical drawings and building computer drafting skills to communicate design concepts clearly.\"},{\"question\":\"Which outcomes are students expected to achieve by the end of the course?\",\"answer\":\"Students should be able to use computer-aided drafting tools to create 2D and 3D objects, sketch conics and solids, interpret engineering drawings, and convert orthographic projections to isometric views manually and using CAD.\"},{\"question\":\"How are scales defined and why are they needed in engineering drawings?\",\"answer\":\"A scale represents how an object’s actual size is reduced or enlarged on drawing paper, enabling precise and comfortable representation when full-size drawing is not possible.
