Civil 3d 2016 default pipe flow direction

[lambertb]

Is there a way in civil 3d 2016 to make the default pipe flow direction By Slope? It seems defaulted to Start to End.

Not that I'm aware of.

If you post this up in the idea station, let me know, I'll definitely vote it up!

I did see forum posts starting back in 2008 on the pipe flow direction topic.

Flow Direction and Storm Sewers add-on.  It is necessary to set the flow direction to 'By Slope' before exporting to Storm Sewers.  If any of the pipes has an incorrect flow direction, Storm Sewers will show the downstream pipe as an outfall. As was posted before, right click on the Flow Direction header in the panorama and select "By Slope", then export.  And Kudos to the person who originally posted the fix cited above.
