Unit I
Introduction: Engineering Graphics/Technical Drawing, Introduction to drawing equipments and useof instruments, Conventions in drawing practice. Types of lines and their uses, BIS codes for lines,technical lettering as per BIS codes, Introduction to dimensioning, Types, Concepts of scale drawing, Types of scales Theory of Projections: Theory of projections, Perspective, Orthographic, System of orthographicprojection: in reference to quadrants, Projection of Points, Projection in different quadrants,Projection of point on auxiliary planes. Distance between two points, Illustration through simpleproblems.
Unit II
Projection of Lines: Line Parallel to both H.P. and V.P., Parallel to one and inclined to other, Othertypical cases: three view projection of straight lines, true length and angle orientation of straightline: rotation method, Trapezoidal method and auxiliary plane method, traces of line.
Unit III
Projection of Planes: Projection of Planes Parallel to one and perpendicular to other, Perpendicularto one and inclined to other, Inclined to both reference planes, Plane oblique to reference planes,traces of planes. Planes Other than the Reference Planes: Introduction of other planes (perpendicular and oblique), their traces, inclinations etc., projections of points and lines lying in the planes, conversion of obliqueplane into auxiliary plane and solution of related problems.
Unit IV
Projection of Solids: Projection of solids in first or third quadrant, Axis parallel to one andperpendicular to other, Axis parallel to one inclined to other, Axis inclined to both the principal plane,Axis perpendicular to profile plane and parallel to both H.P. and V.P., Visible and invisible details inthe projection, Use of rotation and auxiliary plane method. Development of Surface: Purpose of development, Parallel line, radial line and triangulation method,Development of prism, cylinder, cone and pyramid surface for both right angled and oblique solids,Development of surface Note: The sheets to be created shall be notified by the concerned teacher.
