I have a client who is requesting their vertical curve to be labeled with the following equation:
V/L = _____
Where. . .
V = the grade change
L = profile curve length
I figured an expression is what I need. I created an cuirve label expression named V-L in which I added the grade change and divided it by the profile curve length, and I set the format to double as so:
I then added the label to my profile curve label style:
However, when I do this the resulting value is always 0.00:
What am I missing?

Increase the precision on the label and you'll get a result. I did a sample that read 0.00, but with greater precision reads 0.00059910.
Dag-gammit!!!!! I was so focused on the everything else except the precision. That's the answer. Thanks!!!
V/L = _____
Where. . .
V = the grade change = A
L = profile curve length = L
A/L = ?
But K= L/A
1/K= A/L
Therfore V/L = 1/K
1/K = the grade change every unit of measure.

Joe,
Thanks for the information. I'm not a PE, just an overglorified draftsman, so I did not recognize that. That's something I'll pass onto my client and see if that works for him as well.
