I can't tell what you want. If you want a penstroke
to be visible, you can't set its width to 0. If you
set the width to 0, then you need to make a closed
contour and use the "fill" command, not "draw".
If you want the effect of a calligrapher's penstroke,
metapost has a "penpos" command to determine a shape
followed by a "penstroke" command to produce that shape.
Despite the name, "penstroke" actually outputs a filled
contour emulating the sroke of a calligrapher's pen.
It would be useful to see an example of what you are doing
(i.e., the actual metapost code) to produce a picture of a
"single-stroke, one-directional curve".
