  8. Not Unique: Choose the orientation NO HIDDEN LINES: ALL LINES ARE SOLID BE CAREFUL WITH VISIBLE/INVISIBLE LINES 40 10 30 45 20 40 ISOMETRIC VIEWS ARE “REALISTIC” WE SHOW WHAT WE SEE ! ANUPAM SAXENA TA101 LECTURE VII ISOMETRIC VIEW: SCALE 1:0.67

  9. TA: What happens to the shape of a circle on the x-y plane ? G = PRxRz = z X = a + rcos Y = b + rsin Z = 0 = y R Q P x x + = O AGz + C = 0 A Ellipse on the ‘isometric Xn-Zn’ plane ANUPAM SAXENA TA101 LECTURE VIII ISOMETRIC PROJECTION
