I am using Geopak 08.11.09.722 Civil Tools --> Corridor Modeling to view and create cross sections. Using the view cross section tool, all Microstation meshes, solids, and surfaces in the 3d file appear in the cross section model view. Using the create cross sections tool, none of these show up, only the corridors or terrain models. Is this the correct behavior? How do I get other 3d modeled items, such as 3d Geopak Drainage nodes and pipes to appear in the cut cross sections.
