Civil 3D: Create Pipe Network Via Object Not Showing Flow Arrow

Applies to:
Civil 3D 2019-2025

Issue:
You are in Model Space and are attempting to Create Pipe Network from Object
 

And the Flow Arrow for the direction of the network is not showing
 

Causes:
This problem is generally caused by the UCS not being set to World

 
UCS set to WCS (World Coordinate System)

 
UCS not set to WCS (UCS is rotated on the Z Axis 35 degrees)

Solution:
If you have changed the UCS from World, save the UCS (so you can get back to it) and then set the UCS to World, then the flow arrow will show up when attempting to create a Pipe Network from Object
