Dear Robert, please don't forget attaching file samples (consider compressing STEP files using 7zip in case if they are large). Regards, Kirill |

Attaching screenshots with expected shape presentation would be also helpful. |

Screenshot attached. Is it possible that there is an issue with the STEP file for the oriented_edge entities? Should the edge_start and edge_end be explicitly defined? |

Thanks for screenshots. STEP translator generates warnings which might indicate some issues with file (don't know if these are important or not):

And produced shape doesn't pass checkshape validation - with unorientable and non-closed errors. |
