A really short one today - a simple demo of a fundamental technique for primary/slab surface creation. The the help of the very new ( release) approximation in the Projected curve feature, and the new ( release) Edit curve feature that let me elevate a curve's degree and manipulate the control point(s) on it, I can not only create an extremely clean surface, but I can (most importantly) keep control over the control point distribution. In this example I end up with a crowned surface that is a single span degree 3 (Bezier) patch. Nice!
