The objective is also to visualize and represent the 3D objects in 2D planes with proper dimensioning, scaling etc. UNIT I Introduction to drawing Instruments and uses. Lettering. Polygons : Construction of regular polygons using given length of a side; Curves used in Engineering Practice, conic sections, construction of conics by different methods, cycloidal curves, epi and hypo-cycloids. Involutes. UNIT II Scales : Vernier and Diagonal scales. Introduction to orthographic projections; projections of points; projections of straight lines parallel to both the planes; projections of straight lines parallel to one plane and inclined to the other plane. Projections of straight lines inclined to both the planes, determination of true lengths and angle of inclinations and traces. UNIT III Projections of planes: Regular planes perpendicular/parallel to one plane and inclined to the other reference plane; inclined to both the reference planes. UNIT IV Projections of Solids Prisms, Pyramids, Cones and Cylinders with the axis inclined to one of the planes. UNIT V Conversion of isometric views to orthographic views; Conversion of orthographic views to isometric views. Prospective Projection.
