UNIT  I            PLANE CURVES AND FREE HAND SKETCHING                           15

 

Curves used in engineering practices: 

Conics – Construction of ellipse, Parabola and hyperbola by eccentricity method – Construction of cycloid – construction of involutes of squad and circle – Drawing of tangents and normal to the above curves. 

 

Free hand sketching: 

Representation of Three Dimensional objects – General principles of orthographic projection – Need for importance of multiple views and their placement – First angle projection – layout views – Developing visualization skills through free hand sketching of multiple views from pictorial views of objects. 

 

UNIT  II           PROJECTION OF POINTS, LINES AND PLANE SURFACES         14

Projection of points and straight lines located in the first quadrant – Determination of true lengths and true inclinations – Projection of polygonal surface and circular lamina inclined to both reference planes. 

 

UNIT  III          PROJECTION OF SOLIDS                                                                15

Projection of simple solids like prisms, pyramids, cylinder and cone when the axis is inclined to one reference plane by change of position method. 

 

 

UNIT  IV          SECTION OF SOLIDS AND DEVELOPMENT OF SURFACES       15

Sectioning of above solids in simple vertical position by cutting planes inclined to one reference plane and perpendicular to the other – Obtaining true shape of section.

 

Development of lateral surfaces of simple and truncated solids – Prisms, pyramids, cylinders and cones – Development of lateral surfaces of solids with cylindrical cutouts, perpendicular to the axis. 

 

UNIT  V           ISOMETRIC AND PERSPECTIVE PROJECTIONS                          15

Principles of isometric projection – isometric scale – isometric projections of simple solids, truncated prisms, pyramids, cylinders and cones. 

 

Perspective projection of prisms, pyramids and cylinders by visual ray method.
