Dear Istvan, The first shape (tube) is not valid, because the shell of this solid is inverted. You can see it analyzing the normals in the view with the following command: normals a 5 Red lines show normals of forward faces, and blue line - of reversed (see attached picture). If we invert the shell fuse operation gives expected correct result. The script in steps to reproduce shows the corrective commands. |

Thank you, false alarm, my fault, sorry. I should have been more careful before reporting. |

Frankly speaking, the shape of the tube is valid. It represents the infinite space except for the place where the tube would be located. So, the result of fuse of original shapes is correct: the cylinder is wholly covered by that infinite shape. |
