Thread generation in a 3DModel for 3DPrinting process.

Hello Catia Experts,
Do you know a possibility how the 3D specifications of a Thread can be generated in a CATIA model to be taken into consideration for 3DPrinting downstream process?
The Thread is set in the specification tree. When exported to step / stl the 3dmodel is not having the thread representation.

Of course, that the Thread representation can be generated with a Helix and Slot / Rib and boolean Remove with the Thread profile, but I'm not looking for such a solution.

Thanks in advance!
