I am currently working on a site with lots of different pipe runs. is it best practice to draw each run into a seperate network? also i would like to know what is the best way to show crossing pipes on a profile view? curently i am creating a network for all the instances of pipe cross overs and setting it as a style that shows up as a circle on profile but invisible on plan. by doing this i have to find the invert level at the crossing point and input the information onto the seperate crossing network. is there a better way of doing this? also any pipe network management tips would be appreciated.
