I have a profile view drawing that was created from data shortcuts of the alignment, profiles and pipe netowrks. I have a style for my sanitary manholes that was setup in CIvil 3D 2007. When I turn on the display for the new Profile Structure Pipe Outlines Component it draws the structures that are affected by the style change at zero elevation.
This behavior only happens in drawings in which the pipe networks are created from data shortcuts.
