3D Cells in Cross Sections Both Dynamic and Cut Sheets

Can not figure out for the life of me how to get 3D Cells to Display in Cross Sections (both dynamic and cut sheets). I have seen these Proposed and Existing ROW Flags, Alignment Centerlines, Walls, Buildings, etc. in so many examples but nobody ever talks about what line styles these live in or what element template to use! Maybe they are and I am just completely missing it! 

Please help!
