Hi there, Thanks for reading this as many will not give two hoots. I have some construction diagrams which I'm finding hard to understand. Please remember all meaurements are in meters. They read:Ex Ground Level = 31m Centreline Level = 32mBut what do these mean?Right, I'll continue with what I don't understand by asking how does a horizontal geometry graph work and how do you understand it?Lastly I'll ask how to understand these terms:V O/Set Right = 0.004 V O/Set Left = 0.007Many, many thanks for reading. Nick
It might help if we knew what the references were in regard to. Someone out there probably knows but some others of us might figure it out or point you in the right direction with a little more information. For instance, depending on what it's pointed at, Centreline level could refer to the centre height of a bridge if that's what you're looking at. As I said the more information you can provide the more we can provide. Good luckBill Alder
