Hi Michael

Just using the viewport display as an example ... I would like to be able to export to .pdf with this look.

Now when I export to pdf the hidden lines are solid and as strong as the outer edges.

Thanks for the lighting tip ... that works.

However, the hidden lines only show as dashed when I zoom in as far as my display allows but when I save the normal sized screen display to the clip board and then import it in PhotoShop the hidden lines are simply faint light lines ... so if I had a choice I would like the hidden lines to display as somewhat thicker than they are now and a little more broken.

cheers,

eric
