This may be useful, although I fear a substantial amount of maths lies ahead!

Thanks!
I'll look at it ---and of course, there was a typo in my post: "For a given Y, how do I calculate the X and Y of the intersection of the cone and the plane? I want to step through it and essentially draw a series of lines along the top of the shape." should instead be:
For a given Y, how do I calculate the X and Z of the intersection of the cone and the plane? I want to step through it and essentially draw a series of lines along the top of the shape.
