i am trying to produce a vertical profile for a 140 km long route. there is a existing pavement and i need to project its vertical. I projected these data to my profile but i cant convert it by create best fit profile command, i think, i cant understand parameters in this command. what is upper and lower envelope and i have vertical curves from 200 m to 1000 m. What will be my desirable and minimum curve length parameters?
Upper and lower envelope is a distance above or below the profile to try and stay with in for the new profile. Desirable Curve is what you would like to have and minimum is the value that you would not go below.
