These registry keys are experimental features. We don't want to keep compatibility with their values, they might change. They aren't stored in the plan, others might see the model differently.HKEY_CURRENT_USER\Software\GRAPHISOFT\ARCHICAD\ARCHICAD <version>\GSModeler\Better GDL Tube TriangulationMaybe Peter can shed some light onto this one

It was/is a Curb/Gutter object that became some sort of obsolete with the creation of the Railing Tool. In this object I faced this weird distortions and work around it by creating a "Pseudo Tube" with individual Ruled segments where the profile joins were perpendicular to the xy plane. It still works, but is full of internal errors, and besides this people found it overkill for the purpose. I recently found a copy of it floating in the internet by a colleague from Mexico.
Yes, the tricky part is the direction of the 0° direction on that plane. It is the projection of the Z axis to the plane, but sometimes is flipped 180° so the tube is less twisted. Sometimes this flipping is not needed for the model, but it can't be controlled intuitively.

There is another problem with streets: in curved sections, they usually are broader than in straigt directions - sections. Here the tube-command comes to its "boarders". The trailing-curve comes into the topic.
