Thick Lines Pen Display Mode After PDF Export

Hi,

I am trying to simplify ways of producing plan drawings and technical drawings for clients at work instead of relying on the limited options of Make2d. I have stumbled upon this weird bug after exporting a layout detail to PDF:

This is a screenshot from the layout detail with the Pen Displaymode

Viewport_PenDisplaymode
Viewport_PenDisplaymode1345×743 63.8 KB

Here the lines are very thin and just as I want them to be.

After I export to PDF I zoom into the same area to find the lines are too thick and detail is lost.

600dpi exported @A3
600dpi exported @A3980×825 24.9 KB

I have set the line thickness in display options to 1px and it is clearly more than one pixel thick in the pdf. Is it possible to have rhino export lines as one pixel no matter what DPI you export it? It seems like it scales the lines - it is still pretty high definition, but the lines are just way too thick.

What does your Rhino SystemInfo command show?

Hej Jacob -

The only way to get an image into the PDF file that looks like what you see in the viewport is to take a screengrab of the viewport and put that on the layout.

To have the PDF output correspond with the viewport or print preview is a feature request that is on the list as RH-46318 but that will take a completely different way of doing things.
