Hi PaQ,

And thanks for your reply.

I agree with you but unfortunately, I don't have a commercial version of T-Spline, and frankly I don't like it so much.
(And I don't use Fusion).

I much prefer Clayoo and I tested it for a while but it's too much expensive...

But for the moment, in order to use Max's SubdDiv, I'm testing reverse SubDiv tools of NVIL and, in general,
I'm trying to model using only quads.
For this particular case, where I don't arrive with my hands, 3DCoat really helps me, with its retopo tools.

I don't know if I already have that modeling practice. Could you please post some screenshot or some simple .obj file,
that shows what you said ?

Thanks a lot and have a nice day.
