+This time the line weight for the path has been parametrized.  Its default value is 1 mm and this can be overridden at the symbol instance level.  We’ve also changed the path’s line cap and line join styles to round.
+
+Note that when the line weight is modified the spacing between the vertical ticks does *not* change.  The path geometry is fixed.  If you want the symbol to get bigger / smaller to account for the line weight then this would be done using the symbol instance scales.  For example, setting the scales to “1 + !LineWeight / 5” would ensure that there is always 5 mm of empty horizontal space between adjacent vertical ticks.
