Introduction

OpenVSP version 3.27 saw the addition of radius to Edit Curve control points. With this feature, users can specify a dimensional radius at a control point rather than approximating a radius with Bezier points. This greatly simplifies parameterizing cross-sections in a way that is much more intuitive to a designer while reducing the total number of points.

Note that the Radius value at a control point is the dimensional radius having been scaled by height and width, not a radius in the untransformed coordinate space of XY points.
