ENGINEERING DRAWING I Semester: AE / CE / ME Course Code Category AME001 Foundation Contact Classes: 30 Tutorial Classes: Nil Hours / Week L T P 2 3 Credits C 4 Maximum Marks CIA SEE Total 30 70 100 Practical Classes: 45 Total Classes: 75 OBJECTIVES: The course should enable the students to: I. Understand the basic principles of engineering drawing and construction of curves used in engineering field. II. Apply the knowledge of interpretation of projection in different quadrants. III. Understand the projections of solids, when it is inclined to both planes simultaneously. IV. Convert the pictorial views into orthographic view and vice versa. V. Create intricate details of components through sections and develop its surfaces. FUNDAMENTALS OF ENGINEERING DRAWING, SCALES AND Classes: 09 CURVES Introduction to engineering drawing: Drawing instruments and accessories, types of line, lettering practice and rules of dimensioning, geometrical constructions, basic geometrical shapes; Scales: Types of scales, units of length and their conversion, construction of scales, plain scale, diagonal scale, vernier scale; Curves used in engineering practice and their constructions; Conic sections, construction of ellipse parabola and hyperbola, special curves, construction of cycloid, epicycloids, hypocycloid and involutes. UNIT-I UNIT-II ORTHOGRAPHIC PROJECTION, PROJECTION OF PLANES Classes: 09 Orthographic projection: Principles of orthographic projections, conventions, first and third angle projections, projection of points, projection of lines, lines inclined to single plane, lines inclined to both the planes, true lengths and traces; Projection of planes: Projection of regular planes, planes inclined to one plane, planes inclined to both planes, projection of planes by auxiliary plane projection method. UNIT-III PROJECTION OF SOLIDS Projection of solids: Projections of regular solid, prisms, cylinders, pyramids, cones. Classes: 09 Solids inclined to one plane, solids inclined to both planes, projection of solid by auxiliary plane projection method. UNIT-IV DEVELOPMENT OF SURFACES, ISOMETRIC PROJECTIONS Classes: 09 Development of surfaces: Development of lateral surface of right regular solids, prisms, cylinders, pyramids and cones; Isometric projections: Principle of isometric projection, isometric scale, isometric projections and isometric views, isometric projections of planes, prisms, cylinders, pyramids, and cones. UNIT-V TRANSFORMATION OF PROJECTIONS Classes: 09 Transformation of projections: Conversion of isometric views to orthographic views and conversion of orthographic views to isometric views.
