18.3.3                    Hyperbolic reflector

To create subreflector in the third sketch, we will use Create an arc of hyperbola tool - on the toolbar, we pick Sketcher −→ Sketcher geometries −→ Create an arc of hyperbola. This tool creates an arc of hyperbola by center, major radius and endpoints. We will create two arcs, with a spacing equal to the reflector thickness parameter.
