Hay Michael just some thoughts..
After reading this article

I think when you talking about making this form using extrude, loft and fillet you are more talking about "Tangent forms"
But I wanted to make more "Curvature" form that is why I used more Blend and Network commands.
Moi is very effective and simple in use when you want to make "Tangent forms". But when modeling "Curvature" forms it needs a bit more experience)

If you're doing heavy "curvature forms", it can often be a sign that you would be better off using a toolset that is more heavily oriented around organic form modeling like polygon sub-d modeling, rather than using NURBS modeling.

NURBS modeling is generally at it's most effective when you're doing more mechanical shapes that are more strongly defined by 2D profile curves and have cut away areas. Organic models frequently do not fit into that category and generally work better with the sub-d modeling toolset instead.

So that's why that kind of modeling has not been a major focus for MoI, because there's a different kind of toolset that is generally more oriented towards doing it.

I do plan on improving various aspects of curvature continuity in MoI in the future though, but really if it's the main kind of thing you're focused on a sub-d modeler is probably just a better fit.

I have some experience in sub-d modeling I modeled in C4D, but Nurbs is more for me. I have no inspiration working with sub-d. So I like a lot the challenge that moi gives to me when I need to make more organic shapes. My brains work and I like it. Nurbs is more clear for me. May be if I will have some complex shapes that I can not make in moi I'll use T-splain in rhino. But I don't make totally organic shapes, I do not model charters or something like this in moi. I preffer more techinical stuff but love Curvature forms for bodies. I just think this way: if any type of Ferrari can be modeled in Moi than it is good for me.

Well, MoI's filleting has up to G 3's, but if the "look" of it is not what you thought you wanted, you have to change the underlying "staight parts" to acheive the look. In other words, you have to know what the underlying straight part should be modeled like to get the "look" after the curvature is applied.

Like using T-Splines. Can you model a bunch of squares together to make the output for a cool, curved surface shape after you apply smoothing? It would be difficult.

BTW: Viacad is working on the next version which should have the sub to nurbs in it! I'm not clear yet whether it will be a "shark only" tool, or if it will be in the pro version also....

Hello,

Have you ever tried VSR Shape Modeling in Rhino? The plugin is pricey but has some great surfacing tools if you need that sort of thing.

This ? 1 400 € ;) http://www.vsr-webshop.com/epages/62439757.sf/en_GB/?ViewObjectID=2052287

Hello,

Yes, that's it. I have been very impressed with the functionality for the cost. Unfortunately there aren't that many surfacing tools out there that are inexpensive.
