Why is it (and is it just me?) that I cna't edit the pipe slope of incoming/outgoing pipes when editing the structure properties. See attached image for what I'm talking about. The properties box indicates that I can by the nature of the shading of the fields.
That's not really an answer John, surely you understand why I'm asking; the advantage of having a unified place to edit incoming/outgoing pipes seems pretty clear to me. The question I have is about the structure properties, when clearly the field should be editiable (it's not greyed out).
