I have a simple right turn lane that I cannot get the corridor to transition out of back to the standard cross section. I'm using a basic lane transition in my assembly, and I've set a polyline at the gutter (where curb attaches) as my target. I've done this many times in the past with no issue. If I remove the curb from the assembly, the corridor transitions properly. What am I missing? I'm sure it's something simple I've overlooked this time.
Any help would be much appreciated.
Thanks,
Justin

The basic lane does not have a target for width.
You will need to use another lane subassembly that does allow for a width target.
My apologies, I didn't mean I was using a Basic Lane for my sub assembly. I'm using a Basic Lane Transition using Hold Slope, Change Offset. Like I said, without the curb included in the assembly, it transitions properly, but when I add the curb it ignores the transition target.
Thanks,

Can you post the drawing or at least a couple of screenshots?
Here are two pdf's showing how if the curb is added, it ignores the offset target. I've never had this issue prior to this, so I'm sure it's something I'm forgetting, but it's maddening.
Thanks,
Based on what I can see, it looks like your lane assembly is targeting correctly, but the added assembly (curb or whatever) is doing something beyond. Can you post pictures of your assembly that you are using?
Ok, I took your file and tried recreating the corridor. I get something similar, so I looked at the way your assembly was constructed. Your assembly is constructed a little weird (see attached screenshots), in the construction sequence it has the curb & gutter and link slope and vert deflection being constructed first. Then the pavement (Basic Lane Transition Assembly was used, I just renamed them so I could find out what was happening) is constructed afterwards. I think what is happening is that the curb & gutter were attached to another lane assembly or link assembly that set their offset distance, then that assembly was removed and something stayed behind, causing the curb & gutter to have a defined offset even though nothing is there.
So I recreated your assembly and it ran without any problems, offsets were where they needed to be.
It looks like you are moving subassemblies around using AutoCAD commands. When you move subassemblies I'd suggest using the Civil 3D commands. In this case select the stuff that isn't targetting correctly, and choose Move To and select the edge of the lane subassembly. Then it will most likely look detached (or a large space between the subassemblies). To remove this gap select a subassembly (note that A and not many), right click and choose remove Offset in Subassembly (or something like it). Then the curb will be attached to the lane rather than the assembly start point with an offset.
I wonder if that happened because I had copied another assembly and changed some sub assemblies around. Regardless, thank you for your help.
Makes sense based on the the pose from sean fahey, when I copied assemblies and moved parts around. Thank you as well.
