STEP 1: BETTER WHEN THE INTERSECTION POINTS ARE NOT OBVIOUS ANUPAM SAXENA TA101 LECTURE XXIII INTERPENETRATION OF SOLIDS TA: CUTTING PLANE METHOD a b b c c d d e e a b b c c d d e e STEP 2: SHOULD KNOW WHAT THE INTERSECTION BETWEEN THE CUTTING PLANE AND SOLID YIELDS STEP 3: COMPUTE THE INTERSECTION STEP 4: PROJECT POINTS OF INTERSECTION TO THE RESPECTIVE PLANES NOTE: TWO POINTS ON THE BACK SIDE TA: DO NOT MISS ANY INTERSECTION POINT
