REQUEST: non parametric bezier curve

Presently, I spend a lot of time importing Rhino models and parts into my sketch-up models (without issues). I have also read though posts by users like Thom Thom on this subject… however, it would be nice to have a non parametric bezier curve tool.

Like so? Extension created by the SketchUp team to add Bezier curve as an option under draw menu. There are several others as well, search the extension warehouse.
