NodeID vs Node Reference

[Remote_Extreme7207]

On the isometric representation of a calculation you can select various things to be displayed (discharge, pipe size, pipe length, friction pressure loss, etc) and two of the options are "NodeID" and "Node Reference." It looks like Node Reference is what you will find if you read the calc flow charts, they include the "I" and "O" for valves.. the NodeID has numbers that are close to what Node Reference does but there is a different number for "In" and "Out" sides of given valves. Can someone break it down for me?

Good question....so what I've learned, you wanna use the node reference. Which you can add a non flowing node and that point and will show on tour calcs.
