Technical display mode issue


I am facing a problem when using the technical display mode.
I changed the technical display mode settings:
I unselected Hidden lines and Edges visibility.
It appears perfectly on screen in the layout or working space:

but when printing, Edges are visible while they shouldn’t, silhouettes are partially invisible and some kind of errors occurs:

It is very annoying, would anyone know how to fix this ?

Thank you very much,

Thank you,


Hi Arthur -

Thanks, I’ve filed this as RH-82109 Print: Vector PDF lines issue

Thank you, Wim

RH-82109 is fixed in Rhino 8 Service Release 8 Release Candidate

1 Like

I have just started having major issues with this exact funcitonality in 8.8
Was working OK (well some issues w=but workable) prior to this…
Now I have whole elements completely missing from Vector output with latest release

… hang on… seems to be resolved by toggling from ‘image file’ to ‘rhino pdf’ back and forth a couple of times

no - hang on… doing that just makes the vector image be exported as an single image (i.e rasterised)

will send support email with file

Resolved with help from Support. Thank you Brian

For those of you not on the Release Candidate update stream, just circling back and confirming that RH-82109 is fixed in Rhino 8 Service Release 8.
