Corridor Feature Lines Get Distorted at Connected Corridor Endpoints

[rampseeker]

  I have two corridors, each created from a separate alignment.
These alignments meet exactly at their start or end points. Each corridor is built independently, with its own baseline and region setup. I'm using the .ExtractFeatureLines() method to extract feature lines from each corridor.

  When two corridors connect at their endpoints, the feature lines at the junction do not follow the actual corridor geometry. Instead, one of the extracted feature lines shows an abrupt vertical spike or a severely distorted bend between the two corridors.

Here's a visual of what I'm seeing

  However, the feature lines extracted independently from each corridor do not continue smoothly.
At the connection point, the geometry becomes distorted, sharply bending away from the expected design.

Why does this happen, and how can I fix it programmatically?

Try to store the Feature Lines in different Site, my experience is, if possible, assign the Site to store Feature Lines that belongs to the same corridor only, don't put any other feature line that extract from other corridor to the same site if they have any intersection.

I tried using FeatureLine.MoveToNoneSite() to remove all feature lines from their sites, and I confirmed that this broke the automatic linkage.

I honestly had no idea that simply placing a feature line inside a Site would make it automatically linked. Thank you so much for pointing this out—I really appreciate it!
