Feature Line to Alignment?

Another possibly dumb question.

I have a driveway that I have modeled with a corridor but now I would like
to go back and add a center island. Using the Webcasts as a guide, I
thought I would make the island a feature line at the surface of the
corridor, and then make an alignment from that. I could then target the
island alignment in the corridor a work magic like the WebCast. All is well
except that I see no obvious way to make an alignment from my feature line.
Wouldn't the process I have listed below be the easiest way to get to what I
want?

1. Design Intersection Corridor.
2. Find optimum placement of center island.
3. Draw center island with 2d polys.
4. convert polys to feature lines at the corridor surface elevation.
5. Create Alignment from Feature lines. (Actually 1 alignment for each side
of the island)
6. Create profile from feature line and alignment.
7. Target island profile and alignment in the driveway corridor, using the
island subassembly I have created, and viola!

The only problem with Viola!, is that I can't seem to find a way to create
an alignment from a feature line?

Thanks, Tim

Tim,

I dont think its possible to create a Alignment and Profile from a feature line. It sure would be nice to create a single feature line and turn it into both an alignment and profile.

I downloaded the file, but XP is trying to "protect" me and won't let me
execute the zip archive.
If I can figure out how to get that done, I'll take a look.

Thanks, Tim

It seems to me that is the most straight forward way to do it also.
Thanks, Tim

Try using this link it works out pretty slick.

Hope it works out for you.
