Corridor Gutter Pan Not Modeling Correctly

ldwarriner — Wed, 11 Jul 2018 18:17:30 GMT

I recently created a corridor with the Primary Road Full Section Assembly. I put in the cross slope of the gutter and when I created the surface it showed the cross slope of the gutter pan. I scaled back the corridor by 10 feet because I didn't need to model that ten feet and when I went to refresh the surface the slope in the gutter is now showing a 0% slope and not the cross slope I need. The assembly still shows a 5% cross slope in the gutter.

Not following what you mean by "scaled back the corridor by 10 feet".

Can you post the drawing? Much easier to diagnose with the drawing.

When you created the Corridor Surface, did you use Links or Feature Lines as your Data Type? If Links, was it Top links? If so, did you turn on the option to Add as Breakline and did you set Overhang Correction to Top Links?

If that still doesn't help, use Feature Lines instead of Links. I like the results better, although it can be a bit more tedious to set it up correctly, being sure you have all your Point Codes properly set.

I’m also curious what you mean by scaled? Did you simply shorten the forty or did you act scale it?

What I meant by scaled back is instead of the corridor ending at 10+00 it ended at 9+90 as an example. I attached the drawing. You can see in the gutter the slope is shown as 0% in the surface but the assembly shows is at a 5%. It is only doing this on the road on the left side of the drawing. The other roads are fin.

By stretching from 10+00 to 9+00 you would have to extend the profile too

The profile was already extended. I am just confused on why the slope in my gutter is shown as a 0% on the surface but the assembly is shown at a 5%.

Are there any targets in use for the gutter?

If you can clarify for me: when you say gutter pan is the a concrete curb and gutter sub assembly?

Yes it is a concrete curb and gutter subassembly

I attached the drawing a couple posts ago.

is the Gutter slope set to "fixed"?

I attached a 2010 version of the file. The weird thing is the gutter slope is okay for the remainder of the corridor except one baseline it is not. I attached a picture of the section editor. It is showing the gutter slope is 0%, even though the subassembly is 5%. I entered a value of 5% and applied it across the baseline, but it still didn't adjust the gutter slope.

Hi @ldwarriner, as @Joe-Bouza suggested I think if you select the curb subassemblies and then on the properties palette change the gutter slope method to Fixed Slope and then rebuild the corridor and the surface it should solve the problem.
