Create Curve (Poly Curves)

Create Super Smooth Polycurves and Conic Sections using technically superior: Rational Quadratic B Spline Curves which remain fully editable along the full length of the curve i.e. you can go back and node edit the curve as you're creating it!
A Polycurve is a curve or line drawn section-by-section with the mouse or a pen (position and click) directly onto the drawing area and either left as an Open or a Closed Curve upon completion
