Alignment lable style to show deflection angle?

I had someone request an Alignment, Geometry Point, Label Style that shows
the "deflection angle" as either right or left at the PI point of an alignment. I imagine this would have to be done with an expression but I'm curious if it is even possible. I looked briefly but nothing jumped out at me.. Sorry being lazy this time.

You can do it through General-Add Label using
Feature- Alignment
Label Type- Tangent Information

And then you can go in and edit the style and set it to either the Delta or Deflection angle.
It won't be part of the original label set, but it will be dynamic with changes to the alignment. Let me know if you need help changing the text contents to show this.

How do you get the left or right?

style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px">

To coin a phrase from the NFL "after further review, the call on the field was incorrect", or only partially correct.

You can label automatically the delta or the PI included angle. I don't see a way to label the deflection right or left automatically.

Did you guys ever find a way to label the Left or Right for the PI? I also need this functionality.
Thanks,

Can you post a picture? I thought about looking at it earlier, but didn't quite get what was being asked.

I'm looking to create a label that will look similar to what is in the circle. The tricky part may be getting the right and left as the guys above stated. Any suggestions will be appreciated. I'm appariantly unable to attach ANY files. So, in brief, the PI deflection angle or delta angle is the angle from the prolongation of the back tangent to the ahead tangent of the intersection of any two tangent sections. Also, the direction of the angle will be labeled Rt or Lt depending on the angle.

To determine if it is right or left I think you will need to use an expression. Take the Start Direction and figure the range of values that would be to the left and to the right start direction. The base values are in radians, and straight up is 0, add and subtract pi from the start direction and adjust for range of values going past 0. That's all I got so far, I'll try to think about it some more this evening.

Here is one way to check if the alignment goes left or right at a PI, I think this is what you are after. There's some expressions that are not needed in the file.

I know it's been a long time since this was posted, but does anyone have any idea why this expression doesn't work in the dragged state? I'm using C3D 2009 and I loaded this expression. It works great until I drag the label off the curve then I get Right and Left displayed at the same time..
Any ideas or has this problem been solved in some other way I don't know about? Edited by: ryanquigley2390 on Dec 5, 2008 8:59 AM
