Reverse Pipe Start and End

I need to flip or reverse the start and end of a section of arch pipe.  I guess I drew them in backwards, thus my labeling is backwards, i.e. upstream invert is lower than downstream invert.


Reversing the flow direction does nothing as the start and end elevations are still the same.


Any suggestions?

Reversing the flow direction makes the pipe slope positive or negative. It will not change the elevations, but it changes which side is used to calc the slope.

After reversing the pipe direction, select the pipe, right click and select apply rules. This should adjust your inverts.
