I could use some help on this. I use a light gray for entities that are for reference. An example on a current plan is showing the plumbing fixtures on the wall and floor framing plans, or showing skylights "above" on plans other than the roof framing plan. However, when I turn off the colors in the drawing file, or when I send it to layout, everything becomes uniformly black. What do I need to do so that in a monochrome print, entities that are supposed to be "background" will show up as a light gray? I'm using X6. Appreciate the help.
