Hello,
some month ago you helped me to blend a 2d-Logo of a hand to a 3d shape.
Now the logo is reshaped. And I got no idea if it is possible to blend the new logo spline of the hand to a blended 3d shape.
Is it possible?

You suggest the solution lies in my own thread?
Perpaps I have to much respect of the tree fingers instead of two...

...hmmm´...

Hi Mala, that type of shape, sort of organic blended together with branching, is usually better done in a sub-d polygon modeling program rather than in a CAD program like MoI.

CAD programs like MoI are stronger where the object is more structured like when it's composed of hard edges and holes and primarily formed directly from 2D profile curves - overall more mechanical type shapes.

The old logo is somewhat not too far away from that but the newer one is even further away from that type of model.

So some other program that is focused more on organic shape modeling like Silo for example, would be a better fit for that shape than MoI.

There's an example of how to do a hand in a polygon sub-d modeling program here:
http://arl.cs.washington.edu/tutorials/handtut/handtutorial.htm

and if you search for something like "sub-d hand modeling" you can find others, here's one for Blender:

You can kind of get an idea from those how you would form a blocky outer hull formed of all 4-sided polygons and then subdivision smoothing blends all those together.

Sub-d modeling programs are specifically focused on constructing organic shapes with this technique unlike MoI.

As Michael said, subd is a better solution.

But if you still want use a blend in Moi, you could study the principle using a trimming of edges.
The result is perhaps near of what you want and you could improve it.

Here a rapid test.

And don't forget you can make some rustic but efficient SUD Modeling fully inside Moi !
With the Max functions! ;)

Hi here, my attempt with Blender and the Sub-Modeling approach, using your basic shape in the final model, but I don't know for sure is what you want.
However as already told with the use of Sub-D Mesh modelers like Blender you could get better results in a simple way for this type of 3D models.

Hello to All here in this thread,
thx a lot for your tipps and experiences!!!
Phiros version comes pretty near to my suggestions. Thx. very much, Phiro!!!

If I can make it in MoI I prefer it instead of subD-Modelling.

Best regards...

...ok, made´ some progress.
The shape has to to be made in CNC. I fear there are to much mistakes in the surface. What can I do better?
Best, Mala

That is the goal: an attached hand on a ring.
But...it is not modeled properly. And this is why I cannot do a fitfillet between the ring and the hand.
Do you got a simpler idea bringing the hand similar onto the ring? Or is the answer just to learn model better...

Hmmm´...I just thought about SubD-Model the hand in c4d. But I fear I cannot combine and reimport the c4d polygonmodel to attach it onto the ring in MoI...

...I try that out!
Means...Pilous suggestion of modeling with subDs.

OK - question before starting into a new adventure - subD in MoI:
Is it possible to give out a .stl file for a CNC machine?
I fear: No - because polygons shouldn´t work as .stl., isn´t it?

your subD model inside Moi is in fact a nurbs model so can be exported as usual as STL format! ;)

Or any other formats available!

Thx Pilou for the info! And the link...
Still unsure about the workflow without an GUI of the SudD-Modelling.
Only using the command tabs seems to me a little bit strange

Where is the mistake?

I think the mistake is an internal face.

Much easy to help you if you post the model with the mistake to find it.



If it could help you I made in Moi a Subd with your first hand.
Moi is not the easiest tool for subd, but it's the only one I use now.
I takes much time but patience gives pretty good model.
As last one, you could improve it, because I'm not a specialist in subd.

Have fun...

Hi Mala,

re:

Starting with moi version 4 there is a sub-d converter that will allow you to bring a sub-d model created in a poly modeler into MoI as a CAD surface that can be booleaned and trimmed in Moi same as other surfaces.

That's available in the SubD palette on the side Pane.

Export out the SubD control cage from Cinema4D to an .obj file, then in MoI use SubD > Create > From file:
