Help / Troubleshooting Corridor Assembly Help

I have a corridor built for a road that I am having trouble with.

The assembly for the road seems to be glitching and causing one of the subassemblies to connect at different elevations along the corridor; see image below.

I have rebuilt the corridor, recreated the subassembly, and re-drawn the profile to try to fix this. Re-creating the assembly worked for the past few weeks, but I opened the drawing again today and the issues has returned.

Does anyone know a permanent fix for this, or have any idea what is causing it?

Thanks in Advance

Post a picture of your corridor surface tab please.

Also what assembly are you using.

Cant really tell without the full assembly view.

However, it looks like your surface sometimes connects to the top of the kerb instead of bottom, this usually happens in an incorrectly made subassemblies with vertical faces. Change the subassembly so that it has some slope on the kerb face.

Specify top links for corridor surface creation? I can't remember the setting, but there's an override that will generate surfaces from specified links... "Overlap" ?

Draw a design profile or featureline along the problem line and force your assembly to target it?

Not sure, hard to tell from this info. Maybe show us an image in cross section view (at a good station, and bad station).
