I wanted to draw a sine wave and found this post, but it occurred to me you could just draw it in SketchUp with native tools. Faceted, of course, like SU circles, but good enough for many purposes. You could probably do this with just inferencing, and no guidelines, but I found that prone to errors and not as easy to see.
I had to break down the GIF into three smaller ones to be manageable.
Are the GIFs sufficient, or do they need further explanation?
