Subassembly attachment point through corridor transition

[Anonymous]

I appologize for my ignorance in advance as I am still pretty green when it comes to transitions in corridors.  We have done mostly new subdivisions and all have been normal crowned streets.  Well, we are constructing a new street in the middle of town and i'm having to tie into an existing road on a slope.  

The problem I am having is that I'm using feature lines as targets to transition my lane slope on both sides of the road, (which worked fine), but my daylight/grading subassembly is not following the attachment/hinge point on the back of the curb.  It seems to just be static in relation to the crown of my corridor.  So as the curb elevates the daylight attachment point moves further down the back of the curb, and as the curb loses elevation, the attachement point moves up above the curb etc.  I have been searching the forums for over an hour and cannot find a solution.  I'm sure it's something simple that I am doing wrong.

I have attached an image of the daylight issue

Can you post a dwg file for us to look at?

Do you refer about surface corridor SECTION?

One of the common new user mistakes is moving subassemblies around without making certain that they're connected properly.  You cannot just use the ACAD move command or grip edits subassemblies.  Instead you should select a sub, right-click and use the Move command that appears on the shortcut menu.  These commands in the shortcut menu are specific to assembly editing, they help you to ensure that subs are attached to each other.

To fix your assembly you should move the daylight subs to any random attachment point on the assembly, then move them back to the correct location, ensuring that they attach to the back of curb points.

Thank You!  I frequent them quite often, just never made an account.

That was the issue!  I never use the move command, but I do grip edit frequently.  I have been using civil 3d for 7 years, but only have had to use corridors a handful of times.  Thank you very much for the help sir!
