Rhino doesn't export thiner than 0.13 or Mac?

Hello,

I am trying to print a PDF with lines thiner than 0.13.

With PrintDisplay, all looks good, but when exported with RhinoPDF, it looks like line thickness under 0.13 keeps printing in 0.13.

Hairline isn’t taken into account.

Thank you,

PS : I don’t have this problem on Windows, though I had to manually add the line thickness below 0.13 to the AddData (printwidths.txt)

Hi Tom,

Thanks for the quick response. I have look at these topics but I don’t see any solution.

Or am I mistaken ?

On windows, I’ve found a way around using Abode PDF to export from Rhino, but on Mac, it doesn’t see possible to add Adobe PDF virtual printer. In any case, on both Windows and Mac, the RhinoPDF printer doesn’t print really thin lines.

Now I guess this isn’t such a problem when printing on paper but nowadays almost entirely my work is on computer and PDF.

Thanks
