Hi, I noticed that the hidden lines on my drawings where just solid grey lines, and they would also print out solid grey. I then changed the config 'plot_linestyle_scale' to 2 so that when I print, the hidden lines come out as dashed lines 2mm long. Is there not a way of displaying hidden lines as dashed lines on the drawing on screen? You have to print a copy of the drawing to check the dashed line scale, which seems silly, I want to see dashed lines on screen.
