Hi Pilou,

a bit off-topic, but I used your image and re-created it in MoI and then used ArtForm,
which you also have. In ArtForm you can save the model as bitmap and then prepare
the bitmap for ZSurf.

Please note: I did not used any smoothing brushes, only wanted to show you a quick
way with MoI, ArForm and ZSurf.

(With JDPaint one can save this model also as NURBS model … )

Stefan
