Getting a "Failed Point Outside Surface" Error While Building a Corridor

[cgoood]

Hey,

I'm having problems with Autocad Civil 3d 2012. I'm building a corridor of a curb gutter and sidewalk with a daylight of 2:1 on top of an EG surface. The corridor works for about 3/4 of the length but the last section won't connect the daylight to the existing ground surface. There are multiple sections of the corridor with different assemblies.

Here is a more detailed error report:

I get about 33 of these errors each time the corridor rebulds. I'm not sure whats going on, the corridor has targets set for the surface and still won't connect to it.

Has this happened to anyone else?

show us a picture with the ex surface contours and the prop surface contours or corridor model turned on.

my guess is that the 2:1 is landing past the outter edge of the existing surface and so it is not generating the daylight.

I just figured it out as you replied. There was something wrong with the daylight subassembly. I tried using a different preset subassembly and it fixed the errors.

Thanks for the reply
