Because the underarm sections remain intact, I used the Point from X and Y of 2 Other Points to square down from C46 and C49: Add dotted lines from C46 to C16, C49 to C18 and Shoulder to Elbow, using the Line Between Points tool: Using the Midpoint between 2 points tool, place a point between C16-Elbow and Elbow-C18.
