  3. TA: SELECTED LINE OR GENERATOR METHOD SALIENT FEATURES j j STEP 1: DETERMINE THE VIEW WHERE INTERSECTION POINTS ARE OBVIOUS (WILL BE LYING ON ONE OF THE SOLIDS) k k i i l l a a g g TA: DO NOT MISS ANY INTERSECTION POINT b b 1 c c e e 2 12 STEP 2: USE GENERATORS TO REPRESENT THE OTHER SOLID 11 3 d d 10 4 5 9 STEP 3: EXERCISE CARE IN LABELING AND FOLLOWING THEM 6 8 7 a b, l a b l c c, k k j d, j d e i e, i g g 1 10 7 4 6, 8 5, 9 4, 10 3, 11 2, 12 3, 5 2, 6 1, 7 8, 12 9, 11 ANUPAM SAXENA TA101 LECTURE XXIII INTERPENETRATION OF SOLIDS
