Answer all FIVE questionsin A3 sizedrawing sheetbookprovided.

Use appropriatescaleif necessary,to fit the solutionwithin A3 size.

(5 x 20=100)

1. (a) A point B is 30mm aboveH.P and 50mm in front of v.P. Draw the

projections of the point and determine the distance from thereferenceline.

(i)

(ii) A line AB measuring80mmis inclined at angle of 30 to HP and

45 to V.P The point C is 20 mm aboveH.P and 30 mm in front of

V.P. Draw the projectionsof the straight line.

Or

(b) The mid -point of a straight line CD is 60 mm aboveHP and 50 mm in

. front of VP. The line measures80mmlong andinclinedat an angleof 30

to HP and 45to VP. Draw its projections.

(a) A hexagonalpyramidof side of base30 mm and axis 60mmlongresting

on H.P on oneof its basecornerswith its axis inclined at 35to H.P and

parallel to V.P. The base side containing the resting corner are equally

inclined to HP. Draw its projections.

Or

(b) A coneof basediameter50mmand axis length60mmis resting on HP on

oneof its generatorswith its axis parallel to VP. Draw its projections.

(a) A cone,base50mmdiameterand axis 65mmlong, rests with its baseon

HP. It is cut by a sectionplaneperpendicularto VP, inclined at 45to HP

and passingthrougha point on the axis 35mm abovethe base.Draw the

sectionaltopview andthe true shapeof section.

Or

(b) A lamp shadeis formedby cutting a coneof base 140mm diameterand

170mm height by a horizontal plane inclined at 30 to HP, passing

through one extr.emityof the base Draw the developmentof the lamp

shade.

(a) A cylinder 50mmdiameter and 60mmheight stands on HP. A section

planeperpendicularto VP, inclined at 55to HP cutscylinderand passes

through a point on the axis at a height of 45 mm abovethe base.Draw

the isometricprojectionof the truncatedportionofthe cylinder.

Or

(b) A rectangular prism, sides of base 50 mm x 30mmand height 60mm,

rests with its baseon the groundplane.A vertical edgeis in the picture

plane and oneof the longeredgesof its baseis inclined at 45to PP and

behind it. The station point is 50mmin front of PP, 75 mm abovethe

groundplane andlies in a centralplanewhich passesthrough the centre

of the prism. Draw the perspectiveprojectionofthe solid.
