I've built a corridor using only an Offset Assembly. The assembly represents a new path alongside an existing road and I wanted to use the centerline of the road as the main baseline. I have successfully built the corridor and was able to build the Sample Line and Sample Views. However, I am not able to view the sections in the Section Editor. As soon as I try to get into the Section Editor, I get the error message "No station found". The stations are large, 500+00 and up, so I tried changing the BOP to 0+00, but that had no effect. I tend to think it's a result of not having any subassembly attached directly to the main alignment, only to offset alignments. I'm running the 2011 version.
