Mirror transform fails on thread milling

[SlaveCam]

Doing some tombstone programming so have to rely on transformations heavily. 

- Two threadmilling ops as source (right-handed thread)

- Translate the previous two ops N times

- Mirror the source ops AND the translation op

Why, regardless of mirror parameters (NCI/Geometry/reverse order whatsoever) it always creates left-handed threads for the mirrored translate toolpath whereas the mirrored source ops are right-handed? (this is not a post issue as the toolpath wireframe is incorrect)

Unfortunately I think I mirror image technically would be a left handed thread.

 

Can you mirror create geometry create new ops with geometry.

I would never even attempt it...

You can have mirror create geometry, then redo the op right handed.  More work I know, but it would actually work.
