Drawing Instruments And Sheet Layout

Geometrical Construction

Basic Geometrical constructions, Curves used in engineering practices: Conics – Construction of
ellipse, parabola and hyperbola by eccentricity method – Construction of cycloid – construction of
involutes of square and circle – Drawing of tangents and normal to the above curves.
Visualization concepts and Free Hand sketching: Visualization principles –Representation of Three
Dimensional objects – Layout of views- Freehand sketching of multiple views from pictorial views
of objects

Plane Curves And Freehand Sketching

Orthographic projection- principles-Principal planes-First angle projection-projection of points.
Projection of straight lines (only First angle projections) inclined to both the principal planes -
Determination of true lengths and true inclinations by rotating line method and traces Projection
of planes (polygonal and circular surfaces) inclined to both the principal planes by rotating object
method.

Projection Of Points Lines And Plane Surface

Projection of simple solids like prisms, pyramids, cylinder, cone and truncated solids when the
axis is inclined to one of the principal planes by rotating object method.

Projection Of Solids

Sectioning of above solids in simple vertical position when the cutting plane is inclined to the one
of the principal planes and perpendicular to the other – obtaining true shape of section.
Development of lateral surfaces of simple and sectioned solids – Prisms, pyramids cylinders and
cones.

Projection Of Sectioned Solids And Development Of Surfaces

Principles of isometric projection – isometric scale –Isometric projections of simple solids and
truncated solids - Prisms, pyramids, cylinders, cones- combination of two solid objects in simple
vertical positions

Isometric

Perspective projection of simple solids-Prisms, pyramids and cylinders by
visual ray method
