Hi to all Moi3d users.
I would like first to thank Mickael for his marvelous program.
Since i 've got my V3 licence, i modeled lot of forms and surfaces.
I'm fond of Cad Modeling with Moi!

While playing with a new objet, i found one of his part a bit hard to model.
Here attached the challenge file and pictures.
The product is the LB951 Lavazza coffe machine, (EP951 for the white model)
and the shape I try to draw is delimited with the green splines.

Thank for your help. ;-)

I'll soon post some stuff in order to share experiences with you all.

Best.

Manu.
