Plane parallel to HP Plane inclined to HP at 30 °and ┴ to VP Side // to the H.P. making 60 ° with the VP. Read problem and answer following questions 1. Surface inclined to which plane?______ 2. Assumption for initial position? plane // to ____ 3. So which view will show True shape? _______ 4. Which side will be vertical? ___________ Hence begin with __,draw hexagon ______ X-Y line, taking one side vertical. DESIGNED BY : AKASH SOOD M.I.T.M. (GWL.)
