ToNURBS going haywire

Hi McNeel’ies

This subd goes haywire when converted to nurbs using packing - look at the “inside”. The bulge has some really nasty edges, but if the resulting nurbs surfaces are exploded, untrimmed (all) and rejoined, it looks peachy and no naked edges. Maybe something buggy?

HTH, Jakob

Thanks for the report @Normand. I have an idea of what might be the issue, I’ll take a look ASAP.
