Hi Greg,

Which particular exhibited .pdf outputs do you mean?

The PDF output assumes that you will always want to generate the regular visible lines so there isn't any built in way to disable that for the generated PDF but it is possible to configure it so that they are easily disabled later on.

To do that, push the "Line style options" button in the PDF options dialog here:



Then in the Line style options, set the layer for "Visible lines" to be a custom layer named "Visible lines" rather than the default which is to use the style name. With it configured in this way all the visible lines will be clustered together in one PDF layer and will be easier to turn off later on:




Then when you open the PDF in Adobe Reader, go to the layers pane which is here:




Inside the Adobe Reader layers pane, there will be a layer for "Visible lines" there, click the eye icon on the left side to turn it off and it won't be displayed and should not print when you do a printout:




re: "with only outlines and shading - and only outlines by themselves."

It's probably easiest to just make one single PDF with everything enabled in it and then use the layer pane as shown above to disable or enable any specific thing you want for a particular printout.

Hope this helps!
