1. A point A is 30mm above the HP and 40 mm in front of VP. Draw an auxiliary
front view on an AVP inclined at 600 to the VP.
2. A point B is 30mm above the HP and 40 mm in front VP. Draw an auxiliary top
view on an AIP inclined at 450 to the HP.
3. End of a line AB is 12 mm above HP and 30 mm in front of VP Distance between
the end projectors is 45 mm. Draw its front and top views and determine its true
inclination with HP and VP by auxiliary plane method.
4. End A of a line AB is 10mm in front of VP and 40 mm above HP. End B is 30
mm in front of VP and 10mm above HP. Distance between the end projectors is
45 mm. Draw the projections of the line and project an auxiliary front view on an
auxiliary inclined plane (AVP) inclined to the VP at an angle of 450.
5. End A of a line AB is 10mm in front of VP and 40 mm above HP. End B is 35
mm in front of VP and 10mm above HP. Distance between the end projectors is
40 mm. Draw the projections of the line and project an auxiliary top view on an
auxiliary inclined plane (AIP) inclined to the HP at an angle of 600.
6. Front view and top view of a triangular lamina are represented each by an
equilateral triangle with projections of side AB perpendicular to XY line in both
elevation and plan. Draw the true shape of the lamina if the side in the projected
view is 50mm (PTU Dec 2002)
7. A regular pentagonal lamina JKLMN of 25 mm side rests on HP on its corner M
so that the plane of lamina is inclined to HP at 450.Draw its projections by
auxiliary plane method.
8. A regular hexagonal lamina ABCDEF of 20 mm side rests on one of its sides on
HP such that the plane of lamina is inclined to HP at 450.Draw its projections by
auxiliary plane method
