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.

Thanks to you Zarkow for your feed back.

I'm going to try something that way ;-)

I'll post as soon as I can fit with this interesting shape.

So I try the loft option, but on the othe way ;-) (blue lagoon splines)

(I tested the gordon method but loft is better here)

Something does not work well - (see the red circle). I keep on working on it to get a better shape here.

See you.

Manu.

When lofting organic shapes it is usually best to use the loft>loose>exact method and reduce the amount of curves necessary to create the shape to as few as possible.
You also get the best surface if each curve used to create the loft has the same number of points on it.

Other lofting options quite often create tensions in the nurbs surface which create the distortions you are seeing.

Hi Manu, yes I'd agree with kevjon above - try using the option for "Loft Style: Loose" which will be in the upper right command options area when you run the Loft command.

It will make a more relaxed surface that is just generally guided by the inside curves rather than forced to go through every single curve. When the loft is overly constrained by trying to be forced through every single curve that are close to each other it can easily lead to bumps and ripples in the surface.

Hello Manu,

maybe You can make it also with a blend (red)- a big surface with a simple network (blue curves) and a helper surface (green) to control the curvature and direction of the blend!?

Kind regards
Karsten
