FeatureLine based Corridor Baseline results to hidden Alignment & Profile exposed through API !!!

I develop a custom Civil 3D plugin to export alignments, profiles and corridor cross sections to LandXML.
I used a dwg with various cases for testing.
There was a case of a Corridor that uses a Feature Line for Baseline.
When getting Alignments and Profiles i found out that Civil 3D creates a hidden Alignment and Profile for this Feature Line !!!
The Profile type although unnamed has an enum value of 5 !!!

Civil 3D tip. Feature lines vs 3D polylines as corridor target lines

3D polylines can be used as corridor target lines.
Each one gets a name from Civil 3D and the user can not set it or change it.
But if you break it then both new parts keep the same name. And this is a problem when using them as targets.


The only workaround i found is to convert them to feature lines. Names are always unique even in case of breaking and can be set and changed by the user.
