get corridor section from point picked

[Anonymous]

I've requested this before, so I'm kind of rechecking.
If I have a Corridor set up, and want to know the shape of the road section at a station along a baseline alignment, can
it be done via the API?

Normally, you would do this by cutting the surface created by a corridor, and looking at the profile, but that suffers
in horizontally curving areas. The problem is the user will pick points to label based on an arc, while the steep curb
surface "chords" behind the actual curb line.
I'm basically looking to get an alignment/assembly based TC elevation, if I pick a point on my curving curb line in
plan.
I guess I could dig through the corridor and find the region I was in, then dig through the assembly to see what is
going on in that region.
Is there a faster way to tell what region I am in, and what the section is doing there relative to the baseline that
defines it?

Hi James,

In the 2008 api's you can add a corridor section at a specific station. After you have a station built at that location, you can then crawl the section information to extract the calced values you are after.

Yes this requires a corridor rebuild, but it will get you the data at the location you are after.
Thanks

hey, that is close, thanks.
Thing is, the user wanting to know the section will not have write access to the corridor.
Oh shoot, just remembered you cannot dref a corridor.
Dang, what a shame.

They only wont have access if you dont give them access. You could still open the dwg readonly, make the mod to the corridor get the information and then store it in whatever crafty label you have dreamed up.

right, but that is extreme compared to having access to the object via dref.
speed if the problem there, I'll keep thining about it.
