Pipe network alignment profile

I’ve got a pipe network drawn out. I’ve got a centerline profile created and everything (pipe network, centerline, etc) is showing in the profile view. The only thing I can’t get to display in the profile view is the surface profile over the pipe network. I’ve created a second alignment from the pipe network and created a profile for that alignment, both of which are showing in prospector, but when I go to the profile view properties, I’m not given the option to add the pipe network alignment profile.

What am I doing wrong?

ETA: ok, I managed to get the profile over the sewer to show by creating a second profile view specifically for that alignment and then using the “superimpose profile” function. Is this the best way to do this?

From the two responses I’ve gotten, I think the work I did in my ETA is the correct method. Leaving post up for any other newbies in the future lol.
