1 The top view and front view of a straight AB measures 70 mm and 58 mm respectively. The straight line AB is inclined at an angle of 35° to horizontal plane. The end A is 15 mm above horizontal plane and 12 mm in front of vertical plane. The other end B is in the first quadrant. Draw the projections of the straight line AB. Find its true length and true inclination with vertical plane, also show its vertical and horizontal traces.
