FredoSpline - Overview
FredoSpline is an extension for Sketchup 2017 and above.
It creates various curves based on control points, which can be further edited:
Bezier and Nurbs
Fit Spline
Polycorner (corners can be shaped with arcs, bezier, chamfer, dog-bone, T-bone junctions)
Polyline with optional division patterns
FredoSpline is a full rework of my old BezierSpline extension.
