Profile beyond Cul da Sac

[tim_newsome]

My Alignment stops at center of Cul da Sac to allow adding an additional baseline to the corridor for assemblies to grade the Cul da Sac.

I want my Profile to continue so proposed topo tie with existing topo get shown.

What's the best method for this?

Depending on the situation, I typically create a gutterline alignment and profile for my cul de sac. I will already have my assembly showing only curb to existing grade created when making my assemblies. I will create a new corridor design using this assembly around that gutterline alignment. Once that's done, set you main road centerline to target the gutterline alignment or feature line and it should grade out.

Not sure if there is a better way than this but its what I have done in the past.

Iceberg, I got some good insight to how I may do some things in the future.

I left out some clarity to initial question though. I am wanting the show the profile as if the alignment had another 100' extension to it.

I am thinking the best plan would be to create a new alignment where initial alignment ends (center Cul da Sac) and draw at same bearing as road centerline. Then add that as a new profile to the profile view I am extending.

Does that make sense?

[Iceberg]

Why not just adjust the alignment to add on the additional 100 feet.

I want the EOP assembly to target the center of Cul da sac on one side and grade out on the other side with one simple assembly. If I extend the alignment from 18+38 to 19+38 then my EOP assembly won't sweep around 18+38.

I have my alignment extend past the cul-de-sac to enable displaying profiles and surfaces along the length of the profile view. As once you go past your alignment, the profile view does not show any additional data.

Therefore, my assembly along the road stops at the beginning of the radius returns going into the cul-de-sac. From there, I create another alignment for the perimeter of the cul-de-sac which I assign a profile and assembly to for the corridor modeling. I'll then show the surface within the profile view. You could also project (probably the wrong term here) the cul-de-sac profile to the profile view associated with the centerline alignment.

I too model my corridor such that the Cul-de-sac is comprised of an Alignment about the edge of pavement, and the Assembly for said Region Targets the roadway Alignment, and grades out to R/W line, pond, etc.

How you get that to depict in your Roadway Alignment's Profile View is really quite simple... Just turn on your Corridor's (Top) Surface, and show that in Profile View, with the appropriate Style applied. I do not recall if an extended Alignment's Profile superimposed is needed (it's been a while since I've had this exact situation crop up).



FWIW - You can also extend the Profile View's end station (in Profile View Properties) beyond your Roadway Alignment's stationing as well, in order to 'show more' beyond the terminus of the stations depicted in your Sheet drawing's Plan view (i.e., for Plan and Profile sheet).
