Rhino prints lines which shouldn't

Hey all!

I’ve a couple of issues with Rhino 8 and printing detail views.

I created a custom display mode and only turned on the visibility for curves.

When I PDF-print it in vector mode, some surface edges and silhouettes are also printed.
When I PDF-print in raster mode, it works - but it’s a must have to have a proper vector graphics.

Hi Benjamin -

There is a big difference between “technical” display modes and the “regular” display modes when it comes to printing to vector PDF in Rhino 8. Please post a simple 3dm sample and the ini file of your custom display mode.
