Dear @stevebaer and dear @John_Brock
did you have a look at the other topic i posted already above ?
not test if anything was updated for the last SR’s … but for me it does not only look like a “how is line width or weight” displayed on screen vs. paper.
In the post above i created some lines in rhino and checked the result in Adobe Ilullustrator and Affinity Designer…
for me it looks like line width below certain threshold are rounded up somewhere between the actual properties of the curve in Rhino and the output in the pdf.
thanks for improving this aspect for screen and for pdf export.
kind regards -tom
