Very simple. Since you are trying to make a cylindrical line between points
1 and 3 and the center is 2, the distance between point (1 and 2) and (2
and 3) should be equal. This could be your solution.
lc = 1;
Point(1) = {0, 50, 0, lc};
Point(2) = {90.0,-42.0,0,lc };
Point(3) = {180.0,50,0,lc};
Circle(1) = {1, 2, 3};
