Unit 1 DRAWING OFFICE PRACTICE AND DIMENSIONING
1.1 Drawing Office Practice
Importance of engineering drawing as a graphic communication–drawing practice as per BIS code–drawing instruments: drawing board, mini-drafter, compass, divider, protractor, drawing sheets, drawing pencils, set squares etc., – title block– layout and folding of drawing sheets. Lettering and numbering as per BIS –importance of legible lettering and numbering–single stroke letters–upper case and lower case letters–slanting / inclined letters–general procedures for lettering and numbering–height of letters–guidelines–practices. Scales–full size scale, reducing scale and enlarging scales (Description only).
Dimensioning – need for dimensioning–dimensioning terms and notations as per BIS – dimension line, extension line and leader line – dimensioning systems – methods of placement of dimensions – uni-directional and aligned systems – important dimensioning rules –dimensioning of common features – diameters, radii, holes, chamfers – addition of letters and symbols – parallel, chain and progressive dimensioning – practice of dimensioning the given drawing as per BIS code (one view of the object).
Unit 2 GEOMETRIC CONSTRUCTIONS AND CONSTRUCTION
2.1 Geometric Constructions
Bisect a straight line – bisect an arc – bisect an angle – divide a straight line into any number of equal parts – divide the circle into number of equal divisions – construct an arc touching two lines at any angle – construct an arc touching two arcs
2.2 Construction of Conics
Conic sections – definition of locus, focus, directrix, axis, vertex and eccentricity – practical applications of ellipse, parabola and hyperbola.
Ellipse: Construction of ellipse by concentric circle method, rectangular method when major and minor axis are given and eccentricity method when focus and directrix are given–exercises in practical applications.
Parabola: Construction of parabola by rectangular method, parallelogram method when major and minor axis are given and eccentricity method when focus and directrix are given – exercises in practical applications.
Hyperbola: Construction of hyperbola by eccentricity method when focus and directrix are given – exercises in practical applications.
Unit 3 PROJECTION OF POINTS & STRAIGHT LINES AND CONSTRUCTION OF SPECIAL CURVES
3.1 Projection of Points and Straight Lines
Projection of points – position of a point on four quadrants and on the reference planes – system of notation–Place a point on four quadrants with different distances – exercises.
Projection of straight lines–line in the first quadrant and on the reference planes – parallel to one plane and perpendicular to other plane – inclined to one plane and parallel to the other plane – parallel to both the planes – simple exercises.
3.2 Construction of Special Curves
Definition and construction of cycloid – epicycloid – hypocycloid – involute of a circle – Archimedean spiral for one revolution – helix – practical applications – exercises.
Unit 4 ORTHOGRAPHIC PROJECTIONS
4.1 First Angle Projections: Simple components
Introduction – projection terms –orthographic projection – planes of projection – principal orthographic views – designation of views – four quadrants – first angle projection – third angle projection – symbols and arrangement of views for first angle and third angle projections –comparison –Simple exercises in first angle projection with minimum two views of simple components (Without curves and circles).
4.2 First Angle Projections only: Engineering components
Draw the projections of the simple engineering components using first angle projection – exercises in drawing orthographic views – three views–front view, top view and right / left side views. (For Board Examinations any two views can be asked.)
