Q15: A pentagonal prism of base side 30 mm and axis 60 mm has one of its rectangular faces on the H.P. and the axis inclined at 60 to the V.P. Draw its projections.

Solution:

Steps :

1. Draw pentagon of side 30 mm in initial F.V. (Such that one of the rectangular faces lies on xy .)
2. Project all the points in initial T.V. of axis length 60 mm.
3. Inclined the axis of initial T.V. to 60 with xy (or V.P.) This is final T.V.
4. Project all the points above xy line with the help of final T.V. and initial F.V. draw final F.V.
