I’m trying to export / print 3D models in black&white with vector lines without using Make2D.
In the example below, I used an modified displaymode “Technical Linestyle” to accomplish the desired visual outcome.
The viewport looks fine, the preview when using RhinoPDF printer in Raster mode also looks perfect, but when switching to Vector output, the model shows partly transparent.
Note that it doesn’t show the full model as a wireframe, see the example when using the default Shaded display mode as a reference.
To me it seams the Technical Viewmode is showing some hidden / back edges randomly.
Somebody got a clue what’s happening and how to fix this?
Sorry for the late response. I created a new model from scratch, repeating the issue shown before. See the attached .3DM. Vector-print_testmodel.3dm (55.8 KB)

The fix for this issue was committed into the 8.20 branch of Rhino 8. A first public release of 8.20 as a Service Release Candidate will become available on Tuesday May 13th. If this is something that you urgently need, I could send you an internal version with the fix in it, but those are very little tested and could be unstable. An alternative would be to go back to 8.13 but many bugs were fixed since then…
