Ok..So I have a feature class of lines (with z values) and a feature class of multipatch buildings. When I drag and drop the FGDB in the Viewport, it gives me the option to select the lines and multipatch. However, the data does not show up in the scene even though it is listed in the "scene.cej" window with the terrain and street network datasets. How do i fix this? (I have everything in the same Coord. Sys. and everything shows up in ArcScene with no problem).
