Projection of points - Projection of 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.

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

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.

Principles of isometric projection -isometric scale -isometric projections of simple solids, truncated prisms, pyramids, cylinders and cones. Free hand sketching: Representation of Three-Dimensional objects -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 drawing. Perspective projection of prisms, pyramids and cylinders by visual ray method (Not for Examination).

Drawing of a plan, Elevation and sectioning of security room and residential building (Two bed rooms, kitchen, hall, etc.). Practicing design in the CAD Software (Not for Examination).
