Syllabus Engineering Graphics [ESC-103-MEC] Credit Examination Scheme : 02 01 CCE : 30 Marks End-semester : 70 Marks Term work : 25 Marks Unit I Fundamentals of Engineering Drawing and Projection of Point and Line Fundamentals of Engineering Drawing : Introduction to drawing instruments and their uses, Drawing sheets sizes and their layouts, Types of Lines, Dimensioning methods, General rules of dimensioning. Projection of Point and Line Theory of projection - Projection of points in all possible quadrants. Projection of line when parallel to both the reference planes, Projections of lines when it is perpendicular to one of the reference planes, when line is inclined to one and parallel to other reference plane, Line inclined to both reference planes (first angle projection). (Chapter - 1) Unit II Projection of Plane Introduction, Projection of plane when plane is Parallel to one and perpendicular to other, Projection of plane when plane is inclined to one plane and perpendicular to other Projections of planes when it is inclined to both reference planes. (Chapter - 2) Unit III Engineering Curves and Development of Lateral Surfaces Engineering Curves : Conic Sections- Ellipse, Parabola and Hyperbola by directrix and focus and rectangle method, Helix (one convolution) on Cylinder and Cone, Cycloid, Involute of a circle, Archimedean spiral ( one convolution) Development of Lateral Surfaces : Introduction, Method of development, development of lateral surfaces of right solids, cube, prisms, cylinder, pyramids, and cone.( No sectioned solids ) (Chapter - 3) Unit IV Orthographic Projection Introduction, Principle of projection, Plane of Projection, Method of Projection, Orthographic Projection, First and Third angle method of projection, Hidden features, curved features, circular features. etc. Typical problems by first angle projection method (Chapter - 4) Unit V Isometric Projection Introduction of isometric projection, Isometric lines, planes, non-isometric lines and planes, Isometric scale, Isometric projection and view, Construction of isometric view/ projection from given orthographic views. (Chapter - 5)
