i managed to model this weird tube which comes from an offset process of a filletedge surface. Tube has weird control points. i tried “TestRemoveNakedMicroLoops” “untrimall”.
i noticed that, even if the tube diameter is 10mm, i need to “extend surface edge” minimum 10000 to see a difference.
this may be a bug or a bad modelling approach, i like to hear your thoughts.
