Are you talking about screen or postscript output? On my machine,
screen graphics seem to behave as though the thick value is rounded to
the nearest integer, while postscript output with real thick values
creates lines with proportional thicknesses (according to CorelDraw,
after importing):

thick line weight (inches)
0.2 .00129
0.4 .00207
0.6 .00286
0.8 .00365
etc...
