I forgot. Please explain to me again why mainlines, laterals and sleeves are in the F/X Irrigation tab but drip supply and exhaust headers are not. What is the difference between a sleeve and a header? Both are not sized. Both need descriptions and linetypes/layers. Why do I have to open a different tab and generate a separate schedule? Why do I need two separate schedules? It would be cleaner if we don't have a separate schedule with two items in it. Wouldn't it?
