AutoCAD Civil 3D

[#1]

Can anyone explein to me why gaps created where the regions of intersections joins? The daylight feature line stop connecting . See the attached picture. How i can resolve it?

[#2]

You should be able to grip edit the corridor region boundaries to extend them so that they touch. 

[#3]

They seem to touch. I must overlap the regions to connect them. And if i done that the intersection and corridor needs to update. When i update the gaps came back.

[#4]

Although I like the intersection tool for adjusting profiles, I don't like how it creates the return alignments, we get gaps as well. Our work around to this is to modify the return alignments to have 10' tangent sections on each end.

[#5]

The gaps usually appears between the curb return and the full section region. How it will help to modify the return alignment in the end?  The problem is not appear in the end. Also i want to ask you if you modify only the return alignments or you modify the offset alignments too? After your modifications you rebuild the corridor or you update regions and rebuild corridor? If you done the second the modifications still remaining?

Thank you
