Contours with flat spots

I imported topo into a project, and where the contours cross a drainage swale they are flat instead of following the original contours. Is there a breakline option in Revit? If not...any suggestions on how to fix?

Thanks

Revit isn't particular good with swales and remember the site in revit in mainly a design aid, it is not to take the place of civil drawings. You won't beable to get exactly what you want (you can always draft over any areas that aren't quite right.)

That being said, try picking the topo surf and adding another point at the elevation of the contour line right in the middle of the flat area and just to the right(make it slightly higher elevation, then push it around and see if you can get the "V" shape you want.
