Course Objective: Engineering drawing being the principal method of communication for engineers,
the objective is to introduce the students, the techniques of constructing the various types of
polygons, curves and scales. The objective is also to visualize and represent the 3D objects in 2D
planes with proper dimensioning, scaling etc.
Unit I
Objective: To introduce the students to use drawing instruments and to draw polygons, Engg.
Curves.
Polygons: Constructing regular polygons by general methods, inscribing and describing polygons on
circles.
Curves: Parabola, Ellipse and Hyperbola by general and special methods, cycloids, involutes,
tangents &normals for the curves.
Scales: Plain scales, diagonal scales and vernier scales

Unit II
Objective: To introduce the students to use orthographic projections, projections of points & simple
lines. To make the students draw the projections of the lines inclined to both the planes.
Orthographic Projections: Reference plane, importance of reference lines, projections of points in
various quadrants, projections of lines, line parallel to both the planes, line parallel to one plane and
inclined to other plane.
Projections of straight lines inclined to both the planes, determination of true lengths, angle of
inclination and traces.

Unit III
Objective: The objective is to make the students draw the projections of the plane inclined toboth the
planes.
Projections of planes: regular planes perpendicular/parallel to one reference plane and inclined to the
other reference plane; inclined to both the reference planes.

Unit IV
Objective: The objective is to make the students draw the projections of the various types of solids in
different positions inclined to one of the planes.
Projections of Solids – Prisms, Pyramids, Cones and Cylinders with the axis inclined to both the
planes.

Unit V
Objective: The objective is to represent the object in 3D view through isometric views. The student
will be able to represent and convert the isometric view to orthographic view and vice versa.
Conversion of isometric views to orthographic views; Conversion of orthographic views to isometric
views.
