In general, it provides necessary information about the shape, size, surface quality, material, manufacturing process, etc., of the object. It is the graphic language from which a trained person can visualize objects.  \nDrawing Instruments and aids:  \nThe Instruments and other aids used in drafting work are listed below:  \n􀁸 Drawing board  \n􀁸 Set squares  \n􀁸 French curves  \n􀁸 Templates  \n􀁸 Mini drafter  \n􀁸 Instrument box  \n􀁸 Protractor  \n􀁸 Set of scales  \n􀁸 Drawing sheets  \n􀁸 Pencils  \nDrawing Board:  \nUntil recently drawing boards used are made of well seasoned softwood of about 25 mm thick with a working edge for T-square. Nowadays mini-drafters are used instead of T-squares which can be fixed on any board. The standard size of board depends on the size of drawing sheet size required.  \nMini-Drafter:  \nMini-drafter consists of an angle formed by two arms with scales marked and rigidly hinged to eachother .It combines the functions of T-square, set-squares, scales and protractor. It is used for drawing horizontal, vertical and inclined lines, parallel and perpendicular lines and for measuring lines and angles.  \n\n|  |  | MRCET(UGC AUTONOMOUS) | Dept. of Mechanical Engineering | Page 1 |  |  |\n| --- | --- | --- | --- | --- | --- | --- |\n\nInstr","cbCaivPtlYKM3olz","https://ap.wps.com/l/cbCaivPtlYKM3olz","pdf",5235252,96,"English","# Contents\n## I Introduction To Engineering Drawing\n## II Projection of Points and Straight Lines\n## III Projection of Planes and Solids\n## IV Isometric axes, lines ,planes and Solids\n## V Orthographic projection","[{\"question\":\"What is engineering drawing according to the manual?\",\"answer\":\"Engineering drawing is a two-dimensional representation of three-dimensional objects.
