AutoCAD Civil 3D

[#1]

It seems as though the surface is being cut off.  How can I fix this from happening?  See attached picture.

[#2]

It might be one of your subassemblies.  Attach an image that shows your assembly and describe which subassmeblies you've used.

[#3]

starting from the left of the assembly:

1 General Daylight

2 Basic Lane

3 Basic Lane

4 Basic Lane

5 Basic Lane

6 I tried linksloptosurface here but did not get the result I was looking for.  Still trying to find one.

[#4]

How did you create your surface boundary?  You should have used "Corridor extents" or the feature lines dayight on one side and the road edge on the other..

[#5]

The picture attached is the boundary that I am using.  How do you use Corridor Extents?  Yes one side is daylight and the other is a lane subassm.

[#6]

That image doesn't tell me anything.  how did you create that boundary?

[#7]

I created the boundary by setting it to daylight the top links.  Is this what you mean?

[#8]

Yeah, that's what I mean. I'm not sure how you could have specified daylight as a boundary since you only have daylight on one side.

Remove that boundary and use the interactive option then follow your outermost feature lines until the boundary is closed.

[#9]

Ok.  Thank you.

[#10]

If you have 2013 you could select corridor extents as a boundary. If 2012, that option comes if you have more than one baseline...even if that other baseline is blank (hint).
