Insert positions of the idealized models. (a,b) Are the front views of the model. (c–e) Are the front-right-top view of the model. Point O is the intersection of the centerlines of the RPA and SVC. Point A, B and C are insert positions. Point P is the midpoint of the entrance of RPA. (c) Shows the relationship of point A, B, C and O (∠AOB = ∠BOC = 30°). (d) Shows the insert directions: three insert directions point toward point P. (e) Shows the difference of positions and directions of the three insert points.
