Hi All,

I have two splines that define cross sections of a body at different planes

(like the lines drawings of yacht or airplane). Each of the two splines

define a shape that are approximately elliptic (actually its a conic). The

two splines are approximately concentric (i.e. one is inside the other and

they don't overlap).

On the inner spline I have drawn a tangent to the spline at some arbitrary

point.

The problem I am trying to solve is how to find the point at which a

second tangent intersects the outer spline when the second tangent is

parallel to the first on the inner spline.

Anyone got any ideas ??

Thanks,

Steve
