Shaded views don't plot

[Anonymous]

I've a drawing created by our application and on the layout tab some viewports.

If I try to plot two of them with shademode set on shaded tith edges they are plotted empty even if I can see 

a correct preview.

what I need to change to see them plotted?

It plotted correctly for me using AutoCAD 2015 64 bit on Windows 7. Maybe you are running out of system resources, or perhaps your graphics driver is failing?
