Hi Metin,

i exported from MoI as high-density triangle mesh and was able to
use QuadrFlow with the -sharp option on the first model. But in
QuadriFlow i used also a higher poly count setting. The second
model failed here too. But for me it makes not much sense to
use also a high poly count setting, to only have many small quads.

But this is no problem for me, because i have ZBrush, in case
i need to auto-retopo a CAD mesh... :-)

Regards
Stefan
