PDF export from Layout 24 loses hidden lines

When I export to PDF the hidden lines disappear- both on the PDF and on my Layout file. I can restore them to Layout by refreshing the model

I made a test layout file with the same SU viewport and it exported with the hidden lines visible

Same thing happens in Layout 23

Am I missing something simple? Thank you for any guidance

If you’re talking about back edges, I think those don’t show when using hybrid or vector output. And you might have the output override on, which turns your raster to hybrid when you export.
