Problem: A hexagonal pyramid with side of base 30mm and axis 60mm long is resting with

its base on HP., such that one of the base edges is inclined to v.p at 45° and the axis is

50mm in front of v.P.

Construction (Fig.6.28)

1. Draw the top view, keeping one side of the base inclined at 45° to xy and the centre of the
   hexagon at 50mm below xy.


2. Obtain the front view by projection, keeping the axis length equal to 60mm.

Problem : A pentagonal pyramid with side of base 30mm and axis 60mm lL'ng rests with an

edge of its base on HP such that its axis is parallel to both HP and v.P. Draw the projection

of the solid.
