Cannot Print to Vector from Shaded all of a sudden

Hi Steve,

At this point I am no longer referring to a mix of raster shading and vector lines from one detail. I suppose I could insert a picture frame screen shot to achieve that, or overlay viewports.

What I’m asking now is why I cannot print a vector PDF from my shaded detail when it only has linework without any raster shading. I swear I used to be able to this but now am so scrambled I don’t know any more
