Surface edge too thick using pen or technical display modes in PDF

All, I need help.

Issue summary:
I’m trying to do our submittal and shop drawings for metal panels completely in Rhino. However, I can’t seem to get the surface edge thickness to get acceptably thin. I know I can just create lines and use those for the view, but I’d really like to just display the surface edges so they are fully dynamic
sheets as the model changes.

Outcome Summary:
My goal would be to make PDFs displaying surface edges as they look in the viewport using the vector print option.

Settings at this point.
Below are my settings and outcomes.

I tried a view variations but this is essentially the technical display mode with every line setting at 1 pixel:

further on another discussion I found the tip to use raster output and match viewport display so these are the print settings:

These screen shots show accurately what we are looking for.

These are the PDF outputs:

Hi Joe - can youi post a preferably small, file here (public) that shows the propblem or send to with a link back here in your comments? I guess we should see exactly what you have.

I notice your gpu driver is a couple of years old it would not hurt to update that fromn the NVidia website. I don’t say it will fix this but printing and GPU are closely tied so you never know.


Thanks for the super fast reply. Checking with IT on the driver situation. I’ll follow up on that later.

I stripped this model of everything except the objects and sheets involved.

Hi Joe - does either of these look like what you expect?

Rhino Print test_PG_Vector.pdf (4.1 MB)
Rhino Print test_PG_Raster.pdf (4.1 MB)


The issue is object type. In the below file if I dupedge on the surfaces I get curves with the appropriate thickness. I seem unable to reproduce this with surface edge.

Yep, got it - 100% I can see the differnce - it does not show so much at reduced size.
