I am having problem while Calculating cross-sections distances to the next cross-section downstream.

I've got the same problem...

Answer 1

I am having the exact same problem.

Answer 2

I had the same problem and error message. I found that the LineType for the left and right flow paths were missing. After adding "Left" and "Right" to the appropriate lines, it worked OK.
