Syllabus
Introduction: Introduction to
technical drawing and its language. Lines, lettering, dimensioning, scaling of
figures, symbols and drawing instruments. (1 sheet practice)
MODULE I
Plain curves: Conic sections by eccentricity method.
Construction of ellipse: (i) Arc of circles method (ii) Rectangle method (ii)
Concentric circles method. Construction of parabola (i) Rectangle method (ii)
Tangent method. Construction of hyperbola (i) Arc of circles method (ii) given
ordinate, abscissa and the transverse axis (iii) given the asymptotes and a
point on the curve. Construction of Tangent and Normal at any point on these
curves
Miscellaneous curves: Construction
of Cycloid, Epicycloid and Hypocycloid, Involute of a circle. Archimedian
spiral, Logarithmic spiral and Helix. Construction of Tangent and Normal at any
point on these curves.
Projection of points and lines: Types of
projections, Principles of Orthographic projection. Projections of points and
lines. Determination of true length, inclination with planes of projection and
traces of lines.
MODULE II
Projection of solids: Projection of
simple solids such as prisms, pyramids, cone, cylinder, tetrahedron,
octahedron, sphere and their auxiliary projections.
Sections of solids: Types of cutting planes,
section of simple solids cut by parallel, perpendicular and inclined cutting
planes. Their projections and true shape of cut sections.
Development of surfaces: Development of
surfaces of (i) simple solids like prisms, pyramids, cylinder and cone (ii) Cut
regular solids.
MODULE III
Isometric projection: Isometric
scale, Isometric view and projections of simple solids like prisms, pyramids,
cylinder, cone sphere, frustum of solids
and also their
combinations.
Intersection of surfaces: Intersection of
surfaces of two solids as given below.
(i) Cylinder and
cylinder
(ii) Prism and
prism.
(iii) Cone and
Cylinder
(Only cases
where the axes are perpendicular to each other and intersecting with or without
offset.)
Perspective projection: Principles of
perspective projection, definition of perspective terminology. Perspective
projection of simple solids like prisms and pyramids in simple positions.
CAD: Introduction to CAD systems, Benefits of
CAD, Various Soft wares for CAD, Demonstration of any one CAD software.
General Note:
- First angle projection to be followed
- Question paper shall contain 3 questions from each module, except from CAD. Students are required to answer any two questions from each module.
- Distribution of marks (Module -I 2 x 16 = 32 ; Module -II 2 x 17 = 34; Module III 2 x 17 = 34 = Total 100)
