Width of Hairline changed

Recently the plotted (and Print Preview) width of curves having a width of “Hairline” has changed to be about 0.5mm. Is this defined in printwidths.txt, and if so, how? Contents of my printwidths.txt look like this:

// Rhino Default Plot Widths
0.13
0.18
0.25
0.30
0.35
0.50
0.60
0.70
0.80
0.90
1.00
1.20
1.40
2.00

Thanks,
Eric

Hi Eric,
These settings should not have changed. I would check the following section on the print dialog to make sure it looks like the following

Hi Steve,

Yes that’s what I have in the print dialog. I was mistaken, Hairlines are plotting correctly.

It seems to be a display adapter thing. Hairline widths with Print Preview on are correct until I zoom in to a specific point then they all go heavy. Interestingly any other line width (say 0.13) does not show this behavior.
