Thanks, I just uploaded new builds for rhino5 and rhino6 with corrected transform and mesh working.
You can get these from the downloads page at www.geometrygym.com
I do seem to get this display error for mesh in Grasshopper for Rhino6 here, but if you bake the mesh you will see it is correct. Rhino6 Grasshopper mesh display disordered
Let me know if you have other problems or suggestions.
Cheers,
Jon
