New to rhino hatches and lines clunky in 2d pdf

When save file to pdf the fine linework and hatches become much thicker, dense and clunky. Using rhino 5 and adobe acrobat. Happens when use layout and print to pdf straight from model. I scale line weights to .005, select press quality, vector…match pattern definition for line weights… Any ideas welcome. Kate

Can you please post a small sample file and instructions to reproduce this?
I do not have Adobe Acrobat authoring tools.
Do you get the same problem with the MacOS PDF authoring tools?

Are you using Raster or Vector when printing?
