This is mainly to understand why, sometimes, you get "spiral unknown" when importing from LandXML.
It often happens when importing cubic or cubicParabola.
We have many cubics in OpenRail Designer.
You must know which one to use. Set Design File Settings>Civil Formatting accordingly before importing: the unknown spiral will be replaced by the one from Design File Settings. Or find/replace the spiral type in the XML file with the name you will find in the XML column below.
