Hi,
I need to label PI, PC and PT stations in my curve labels, as well as E (External Distance).
Is this possible?
This attachment shows the components I need to include in my label:
The components underlined in red are ones I don't see component 'properties' included for - in the Label Properties
When I Edit the Curve Label Style > Layout tab > Text > Contents and get into Properties, I dont see those Properties listed.
Any ideas ?

Solved by wfberry. Go to Solution.
The PC and PT are "Start Station" and "End Station".
The D= is "Delta Angle"
Not sure about PI Station...there is one called "PI Extended Station", that might be it.
I don't know what the E= is in your example.
The PI, PC and PT stations are normally labeled with the alignment.
Beg Sta = PC
End Sta = PT
There are two definitions for the degree of curve listed, chord definition and arc definition. Which one do you use?
(They are both listed.)
I don't know why you would need the E, just the distance from the PI to the curve. We used that back in the day when we used 100' tapes (chain)

I do not see the Beg Sta or End Sta 'properties' as data I can include in my Label. That's the problem.
Here's my sequence:
Select the label > Edit Label Style > Layout tab > Component name > (mine's called 'IDOT Curve Data') > Text section > Contents > click in the Value Cell for Contents > [...] > Properties tab > Properties: pulldown...
at this point, all that shows in the Properties pulldown are "General Segment (various elements)" as in the attached photo
Here's how I get there:
Open the Add Labels box
Feature: Alignment
Label Type: Multiple Segment
Curve Label Style: <our-own-name>... then edit this style.
I think this is a different type of Alignment label than the "Station Label" that gets assigned to the length of the Alignment.
That looks like a regular old curve occurring anywhere, not a curved segment of an alignment. Make sure you're editing an alignment label.
PI Sta around here = PC Sta + Tangent
As for E, you should be able to write an expression for it if it does not appear in the list of parameters in the label composer: E=(Rad/COS(Delta/2))-Rad.
I know that IDOT is probably who is dictating what goes into the curve data, but there are ways. Here in WI Our DOT provides all the design drawings including templates for consultants so that the standards are more likely to be followed. You might check with the DOT to see if they have a curve data label all figured out.
You're right, I had a regular curve by mistake. Changing it to a label for an Alignment curve gave me the components I needed to see.
Thanks!!
Your sequence outline got me to the alignment curve labeling. I was in general curves before by mistake.
Thanks for your help!
Everything you want is there. I'm attaching a file with my curve labels with the Start (PC) and End (PT) stations added as well as the External Secant (External Distance). Note there are two label types, a Curve label for the PI & PT labels i use, and a Point of Intersection label I use for curve data. I don't remember why, but years ago i determined the PI label gave me a better function then curve labels for curve data.
