You'd probably have to make the segments small enough to get close to the desired accuracy, and if you can't do a Slice things might look a little funky. (I'm picturing something like a newspaper box in a subway station - on a smooth curve for the section it would be smooshed or smeared, but with small segments it would be little chunks, or turn off Section for it and end up with a bunch of them from slightly different angles.)
The End view directions (arrow view direction) need to be parallel to each other. It can be done with multiply line segments.
The segmented line would be your cut line and the RH and LH arrow must be parallel to each other for your view direction. You can't have multiple view directions as shown alone your segmented line. The section line can be segmented.
A tunnel...in Inventor...sounds interesting, care to elaborate?
civil3d has a good tool for doing long sections along a pipe route (or tunnel).
