User input in an Expression for Profile Label

[rkmcswain]

Is there any way to allow user input in an expression for a profile label?

Thanks.

I don't know of any way to get any user input into any label other than directly editing the label. What are you trying to accomplish?

Glad you asked.....

In order to correctly calculate the slope, I need to provide the equation with the distance along the curb, not the difference in stations. 

The current line labels are worthless now since the info is guaranteed to be wrong (unless by chance the curb is parallel to the alignment along a tangent - fairly rare in most of our work.)

I know that enabling a user input field is only slightly better since it would still rely on the user to enter the right number -- but it would allow us to define the other label parameters. Currently we just hardcode the label to say [XX' @ 0.0%] so that we know to fix the length and slope.

Thanks.

Aha. So you are labeling the grade of the flowline of your street in the centerline profile view. I'll have to ponder that one for a bit. If I think of something, I'll get back to you. Can you post up a screenshot of what you want? Also, what other information do you have? Do you have a corridor or a featureline for the curb or???

Yes, we need to show true curb length and grade for the left and right sides, while referencing these points to a CL alignment.

Currently we simply calculate the Sta and Elv for each grade break and creating a profile based on those parameters. The profile graphics are fine, it's the labels that fail.

Feature lines do not help since there is no facility to label the feature line segments in profile. We do not want to use profile view labels since they do not respond to changes (for example, if the elevations of the feature line are modified). See this thread for more info on this issue.

Thanks again.

Thats exactly why I trying to get my expressions to work, except I figured I'd label the plan directly to avoid the bogus length and grade quote
