SECTION I
Unit1: Fundamentals of Engineering Graphics& Engineering Curves
A) Fundamentals of Engineering Graphics: Introduction to Drawing instruments and their uses.
Layout of drawing sheets, different types of lines used in drawing practice, Dimensioning system as per
BIS (Theoretical treatment only)
B) Engineering curves: Construction of regular polygons (up to hexagon). Construction of Ellipse – (Directrix-Focus & Arcs of circle Method) Parabola-(Directrix-Focus & Rectangle Method) , Hyperbola-( Directrix-Focus & Rectangular Method), Involutes, Archimedian spiral and Cycloid only.
(10 marks)
Unit 2: Projections of lines & Planes
A) Projections of lines: Introduction to First angle and third angle methods of projection.
Projections of points on regular reference planes. Projections of horizontal, frontal and Profile lines on regular and auxiliary reference planes. Projection of oblique lines it’s True length and angle with reference planes by rotation and auxiliary plane method. Concept of grade and bearing of line.
B) Projections of planes: Projections on regular and on auxiliary reference planes. Types of planes (horizontal, frontal, oblique and Profile planes). Edge view and True shape of a Plane. Angles made by the plane with Principle reference planes. Projections of plane figures inclined to both the planes. (Circle and regular polygon) (15 marks)
Unit 3: Projections of solids
