ECE 2-1 Physics Important Topics
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.
Computer Aided Design, Drawing practice using Auto CAD, Creating 2D&3D drawings of objects using
Auto CAD
Note: In the End Examination there will be no question from CAD.
