I am having an issue with my cross sections not matching my dtm created in corridor modeler in ss3 in areas of horizontal curvature. My template drops are run at 5' intervals and I'm only plotting at 100' so that is not my issue. I have confirmed that the breaklines of the dtm look correct throughout the corridor.
Could you please provide the version number of InRoads and MicroStation that you are using? If it is an older version then it could have been a defect at some point.

microstation V8i select series3 08.11.09.459 Geopak V8i select series 2 08.11.04.615 Don't have inroads installed on my machine that I'm aware of or can find.
ok, so first you really need to upgrade to 08.11.07.615 for GEOPAK. There were issues or defects in previous versions. One was with station equations
I had the same issue, I solved it after changing "corridor design stages" in Civil Standards. You can check this thread.
