I have a project with different disciplines: architecture and MEP. I started the project with the project browser organization showing "all". Then I switched to "disciplines" to have a better order. But I noticed that in the electrical plan, when I switched the discipline from Architecture to Electrical, all the drafting line work that I drew are now showing in light color, kind of "beyond type of lines". Even when I tried to override the color in the line category to black, the line color does not change. The same thing happen with the mechanical Plan.
Other thing that I noticed is that in the category pull down menu I do not see "Plumbing", is there any way to add this discipline to the project?
By the way, I am using revit 2008.
Thanks.
