When I create the hyperbolic curve, it is described the usual mathematical way, with just the values of a and b from the standard equation of a vertical hyperbola. Problem is that Fusion CAD describes conic curves in terms of the rho value and the height and width of the tangent intercepts. I guessed there would be a conversion function. HAHAHAHAHA nope. So I sat and did a load of calculus and trig and algebra, resorting to Wolfram Alpha at one point. All sorted, and here is the first reflector
