3. The locations of six poles corresponding to four successive finite positions (P-P-P-P) of a moving plane are as follows:-
$$P_{12} (70, 75)$$
$$P_{13} (115, 70)$$
$$P_{14} (60, 25)$$
$$P_{23} (120,105)$$
$$P_{24} (90, 45)$$
$$P_{34} (85, 95)$$
(co-ordinates specified are in mm).
Construct the Circle Point Curve for the first specified position of a moving plane.
(Take minimum 8 points other than poles)
Select any two moving pivots other than poles and image poles and locate corresponding center points.
