I'l like to sort an alignment segment table by it direction. I added a start station field into the table but the curve do not get a station, why? Can it be made to do so?

Hi Jay
Thats exactly what I'm trying to do, and I'd like the segment start and end station. And if I could get a reference alignment in it too I'd be golden. What did I miss to get the station of the curves?

I'm assuming you're already aware that step one is to Add "Multiple Segment" Labels to the Alignment.
For the curve stationing, add a second entry in Table Style, here's what the Table Style looks like:
As for the End Station, C3d doesn't do this but I've came up with a pretty good workaround to make it happen.
Add an extra PI to the end of the Alignment 0.001 in length and the end station will display in the table:
For the Reference Alignment thing, can you elaborate on that? Or post a caption, I'm not understanding what it is you wish to do.

So those are likely either Offset or Miscellaneous Type and not Centerline alignments.
I've not used it that way but just tried a quick test of an even 13' Offset Alignment and had no problem
creating a Table of it. Same for a ROW line Miscellaneous Align type.
So I'm thinking the answer is yes you should be able to report those in a Segment Table.
are those the stations of the line or a parent alignment?
here is a picture of what I'm trying to do: Align A is to be tabulated and I'd like align BL stationing to be referenced.

Joe,
Unfortunately they are per alignment from it's BOP, I knew this but fell for the bait since my Centerline alignment started at 0+00
which for me is rare.
@Anonymous I change C/L BOP to 30+00 then yes the Curb & ROW align's begin @ 0+00 from the BOP of those Alignments.
Sorry for misleading you but I can't think of anyway to have them be merely a Sta./Off of the parent alignment.
That just seems all to logical.
Just curious, is your stationing for that secondary alignment in your caption stationing copacetic with the parent beyond the BOP
or is it on it's own stationing after BOP as well?

Joe,
AFAIK, The way C3d stations the BOP for what I call secondary Alignments (Miscellaneous & Offset types)
is to assign 0+00 the BOP.
So if I have my C/L BOP set to 30+00 then even though my "Offset type" curb Left starts @ say 30+33 LT, the BOP
for curb lt is set @ 0+00. And same for my Misc. type ROW rt starts @ 0+30 Rt, the BOP for ROW rt is set @ 0+00.
This is as you know not an issue for Sta. / Offsets off the parent etc. but try to use any of them as independent
and the will be incorrect and by incorrect I mean they will not have any direct correlation.
To be fair here though if the secondary alignments did actually jive with the parent then the software
would have to add station equations etc. as in Highway work to correct up the stationing
every so often.
Using OOTB C3d I can't think of an automated method of creating a table like your after.
The only way I can think of to dynamically show your secondary align in a table is maybe the Sincpac
Dynamic Station/Offset Table could help here?
Haven't tested this but here's what I think may work if you have Sincpac-3d:
In C3d, Create Points Command>Alignment> this will place Cogo Points @ all of your Horiz
align geometry.
Then In Sincpac create a Dynamic Station/Offset Table.
