What command to bring to surface curves but not show if surface should hide them?

Hi,
curves created on a surface, using project, or curves used to make a surface,…, I wish them to be visible on the surface, BringToFront though makes them visible even if part of the surface hides them when I rotate the view, not what I want, I dont want to see the back door when looking at the front of a house for example !

Hi Steve, maybe you could use contrasting colors for the curves. Or even give the surfaces a ghosted display while the curves remain shaded or other. —Mark

I think I misunderstood your request. Not sure how you would do what your asking. Could you move them in a slight direction to the way you want to only see them—Mark

Does reducing testZBiasFactor help here?
