1. Attempt all questions. 2. Make suitable assumptions wherever necessary. 3. Figures to the right indicate full marks. 4. English version is an authentic. Q.1 A pictorial view of an object is shown in fig.1. Draw to full size, its following views using ‘First Angle projection method’. (1) Front View – looking from direction ‘X’ (2) Top View (3) Side View Show dimensions using Aligned dimensioning system. Fig.2 shows two views of an object. Draw its isometric view. Draw the following views of fig.3. (1) Rear view (2) Bottom view OR Draw a right angle only with the help of compass & trisect the same with the compass only. Construct a curve, when the distance of its focus from the directrix is 50mm and its Eccentricity is 3/2. Name the curve. A line MN 90mm long inclined at 30Ă to VP. and 45ĂHP. Its end M is 22mm above HP and 32mm in front of the VP. Draw its projection & find the length of top view & front view. OR Draw an involute to a circle of diameter 50mm. Plan and Elevation of a line AB, 60mm, measures 54mm & 45mm respectively. End A 20mm above HP & 15mm in front of VP. Draw its projection & determine its true & apparent angles. A circular disc of 40mm diameter and negligible thickness rests on HP on its rim and makes an angle of 45Ă to HP. One of its diameter is inclined at 30Ă to VP. Draw its projection keeping distance of center of the disc 40mm in front of the VP. Draw regular Heptagon of 30mm side by three circle method. OR Construct a parabola by Tangent method. When its base 72mm & axis 40mm. A regular pentagonal plane of 30mm side rests of the HP on one of its sides such that it is inclined to the HP at 30Ă and to side on which it rests inclined at 45Ă to the VP. Draw its...
