I created a pressure pipe network from object with 10" pipe. Now I want to add 6" pipes but the pulldown does not show pipe options. The attachment shows the blank window. I can add 4" pipes, I assume that is the default, but I can't swap them. The pipe options show up in the Pressure Network Parts List when I look in Settings.
How can I draw the pipe size I need?
Thanks
