BE 110: ENGINEERING GRAPHICS 

Module Contents Hours
I Introduction to Engineering Graphics: Need for engineering drawing. Drawing instruments; BIS code of practice for general engineering drawing. Orthographic projections of points and lines:-Projections of points in different quadrants; Projections of straight lines inclined to one of the reference planes, straight lines inclined to both the planes; True length and inclination of lines with reference planes; Traces of lines. 14
II Orthographic projections of solids:-Projections of simple solids* in simple positions, projections of solids with axis inclined to one of the reference planes and axis inclined to both the reference planes. 11
  FIRST INTERNAL EXAM  
III Isometric Projections:-Isometric projections and views of plane figures simple* and truncated simple* solids in simple position including sphere and hemisphere and their combinations. Freehand sketching: Freehand sketching of real objects, conversion of pictorial views into orthographic views and vice versa. 9
IV Introduction to Computer Aided Drafting - familiarizing various coordinate systems and commands used in any standard drafting software - drawing of lines, circle, polygon, arc, ellipse, etc. Creating 2D drawings. Transformations: move, copy, rotate, scale, mirror, offset and array; trim, extend, fillet, chamfer. Dimensioning and text editing. Exercises on basic drafting principles, to create technical drawings. Create orthographic views of simple solids from pictorial views. Create isometric views of simple solids from orthographic views. Solid modelling and sectioning of solids, extraction of 2D drawings from solid models. (For internal examination only, not for University Examination). 15
  SECOND INTERNAL EXAM  
V Sections and Developments of Solids: Sections of simple* solids in simple vertical positions with section plane inclined to one of the reference planes - True shapes of sections. Developments of surfaces of these solids. 12
VI Intersection of surfaces: Intersection of prism in prism and cylinder in cylinder - axis bisecting at right angles only. Perspective projections: perspective projections of simple* solids. 9
  *Triangular, square, pentagonal and hexagonal prisms, pyramids, cones and cylinders.Note: First angle projection to be followed.
