Printing to Rhino PDF Linewidths not thin enough. Hairline is too thick

[ambrose_bill]

Firstly. is there documentation which concisely describes the various options relating to linewidths/scaling/display and printing ?
I have spent most of the day trawling through the forum, and bouncing from page to page in the Help documentation. I am now far more confused than I ever was and really have no idea what all the **new features are for or how to use them…

Second (and main point of this post)
When printing to Rhino PDF, the ‘hairline’ linewidths are far too thick.
The ‘minimum weight’ line when printed to PDF is way too thick… Here’s the screenshots.
thinner lines are how it appears in layout window in Rhino / thick lines are the resultant pdf

and here’s with ‘PrintDisplay’ set to ‘ON’ in Rhino Layout

If I export as an .ai file it looks like this when printed to PDF (i.e/ hairline line width is respected)

hi @ambrose_bill can you post a sample file so that I can inspect the settings you have used?

Yes sure… I think it’s related to “imported” blocks from Autocad actually… sorry meant to follow up on this post myself. Subsequently I got the desired effect using wirelines created wholly in Rhino. Apologies if misleading
