PDF line weight became heavy after Rhino 8 upgrade

Rhino Rhino for Windows

I am seeing thick lines in pdf files created by RhinoPDF. The symptoms are eerily similar to those reported in PDF line weight became heavy after Rhino 6 update to SR17 (6.17.19189.16411, 8/07/2019) - #9 by pascal

Could this be a repetition of the regression?

Hi Garry -

Can you post a 3dm file that shows this behavior?

@wim I used the same 3dm file in V6 and V8. I have attached the pdf files from both. RhinoPDF was used for both, at 600 DPI.

Hi @coffsoft

I’ve been looking into this issue, thank you for the files…

Unfortunately, I’m seeing the exact same results between V6, V7, and V8 using your example file. I just installed 6.35, loaded your file, and printed it to a PDF, and thickness matches V8 (note: It does not match your V6 results).

So the next thing I’d like from you is a copy of Rhino’s “settings” file from the respective folder…

For example:

For V6: C:\Users\Garry\AppData\Roaming\McNeel\Rhinoceros\6.0\settings\settings-Scheme__Default.xml

For V8: C:\Users\Garry\AppData\Roaming\McNeel\Rhinoceros\8.0\settings\settings-Scheme__Default.xml

…this assumes your user name is “Garry”… just replace it with the correct user name if it’s not.

Thanks,
-Jeff

Thanks Garry @coffsoft,

This helped me locate the “problem” area… The “Linetypes and Line Widths” section on the Print Dialog have been set to something other than their defaults. Note: These settings are not per-document (or even per-print), they are global “Print Preferences” that “stick” if/when a successful print occurs…so setting them during a print, will be remembered for the next print…even if you’ve loaded a different document…

I’ve attached a screenshot showing what/where I’m talking about. In V6, you’ve set these values to 0.35 and 0.18… but their defaults are 1.0 and “Hairline” respectively. If you just change the “Scale by” value in V8 to 0.35 (like you have in V6), then the results should be the same.

@jeff That is interesting. Is there a reason for this setting impacting curves but not impacting solids? I have added solid stairs to the model. With the scale set to 1.0, the printed lines for the solids are not thickened.

Would it be smart to for Rhino to automatically migrate the setting when upgrading to a new version? Thank you for your help.
