It seems that there is no option for linewidth in parametric_plot. (2D in my case.) Is that true? Any way to make the graph thicker?

parametric_plot takes an argument thickness as follows:

sage: parametric_plot([cos(x),sin(x)],x,0,2*pi,thickness=5)

Thanks. That works (of course). It is too bad that the syntax is not uniform...

Note that the Three.js viewer does not respect thickness on Windows and some macOS.

Instead, use radius to create a cylinder around the curve. See:

We tried to be consistent in that "thickness" specifies a width that does not change as you zoom in and out, while linewidth does visually change as you zoom in and out. If that is not the case, it should be fixed.
