Projection of planes 006

  1. 1. Problem 3: Read problem and answer following questions A 300 – 600 set square of longest side 1 .Surface inclined to which plane? ------- VP 100 mm long is in VP and it’s surface 2. Assumption for initial position? ------// to VP 450 inclined to VP. One end of longest 3. So which view will show True shape? --- FV side is 10 mm and other end is 35 mm above HP. Draw it’s projections 4. Which side will be vertical? ------longest side. (Surface inclination directly given. Hence begin with FV, draw triangle above X-Y Side inclination indirectly given) keeping longest side vertical.First TWO steps are similar to previous problem. a1’ Note the manner in which side inclination is given. a’ End A 35 mm above HP & End B is 10 mm above HP. 60º So redraw 2nd FV as final FV placing these ends as c’ c1’ said. c1’ a 1’ 30º b 1’ 35 b1’ b’ 10 X ab 450 a1 b1 Y a c b c c1 Surface // to VP Surface inclined to Vp
