The black diamond markings are for manufactured truss layouts. A truss can carry a greater load than dimentional lumber, so you need fewer of them. In an 8' span, 5 trusses will carry the same load as 6 rafters or joists.

The diamond is an alternative OC (on center) spacing for framing materials. The diamond OC spacing matches 16" OC spacing every 8' so it is compatible with most sheet goods (plywood, paneling, etc.). The benefit of using the diamond spacing is that you save one joist or stud every 8'.
