Yes. Check the box if you wish to change the condition previously established. Wind, uniform load and allowable stress are all similar in this "carry forward" approach with checkboxes.
I have another question. Is it safe to say that "Crest Distance" more or less the average radios of a hill? The help window says it "Specifies the distance upwind of crest to where the difference in ground elevation is half the height of hill or escarpment."
I'm trying to develop a form that I can give someone to fill out with all the information I need to make a run. I'm hoping to make the wind load sections self explanatory.
