@All - For completeness: https://helpandsupport.xara.com/xara...=line%20widths
Funny how Xara fails to mention zero-width lines do not render. If the result is SVG, you have stroke-width=0. If it is a span Tag, no border attribute is included.Note: A zero width line is a special case, and should not normally be used. This draws a line one device-pixel wide. The actual size will therefore depend on the device the drawing is displayed on. On a monitor screen one pixel is clearly visible and is never shown anti-aliased. On devices such as printers and particularly on image setters, which have a much higher resolution, the line is almost invisible (zero width lines in imported files are converted to 0.25pt).
The last bold part is interesting too. This means you end up with a 0.333px Line width.
