I am brand new to pipe networks. Somehow i have lost the corrugated pipe option when created a pipe network.
I had modified the reinforced concrete pipe selection to read "RCP", was in the process of changing the corrugated metal pipe to "CMP".
after saving my changes, and trying it out, that option is no longer in the list. is there a way to reload the original? or what did i do wrong.
problem solved. went too far with the path to the catalog
