I posted a "limit-case" ;)
If we need just to fill a hole,like in this case,we can use -NSIDED-, or select ABCD edges and choose NETWORK, or select AB like sections and CD like rails and do the SWEEP
all three solutions will make a patch...... without a continuity,this means that if you do a close-up you can see the seam
Different situation if we want to have a continuity of curvature (G2) between the new surface and,at least,BCD surfaces
This is an high-end feature that maybe only ultra-expensive modelers can handle,often called also CLASS-A surfaces (a typical case where this feature is required is car-modeling for manifacturing)
Actually, in MOI,we have just BLEND that allow a continuity choice,now improved with multi-chained edges
if in future we will also have a continuity choice in NETWORK we will able to make cars much more better

Thanks again Michael ! :)

As I know Nsided works with continuity and have to work here or i'm wrong?

Which kind of continuity?
G-0=position
G-1=tangency
G-2=curvature

G1

I just don't know which kind of curvature can handle -NSIDED- tool

Avoiding misunderstandings i cleary speaked about G-2 why? Because it's only option that gives a perfect junction between two surfaces
This means(one more time)that you can't see seams or artifacts in junction area...it's perfectly smooth(continuity of curvature)
If you want better know about, here is a link of SOLIDS++ kernel that MOI use:

http://www.integrityware.com/solids.html

and here some examples of continuity options from them:

http://www.integrityware.com/AdvancedSurfacing/Blending.pdf

I posted that "limit-situation" based upon example of Futagoza (Stefan)
That time,Michael well noticed seams at first close-up and speaked about not perfect junction
I know..NSIDED can handle my " limit-example" but also give a not perfectly smoothed surface

It defenetly use some kind of tangency I assume that it is G1 but Michael knows better.
And in not very complex situation like yours I think it can produce good result.

Sure it produce good results !! :)
It always depend what you want...in advanced modeling usually G1 is not enough
i have read here from an user in the past:Apple wants just G2 filleting in their stuff...(take a look at the edges of I-Phone )
..or imagine to model a car with lot of patches that need to join together without seams ;)
Let Michael to say something,if he's not too busy :)
hope this time no misunderstadings :)

In all my organic tutorials I used G1, because G2 some times produce kinked result and as I can see it all looks good.
All I get from my experience is that G-0 (circular fillet) is look very digital, G-1 more organic, G-2 Super organic. But in most cases G1 is enough.

Yes..sometime G2 could be "too tight" and give unwanted results
Now you can understand better my car-fender video (you asked me ;) )
My target was to have a G2 junction between fender and car-body
I've extracted curves from G2 blend surface
modified points of extracted curves withouth touching G2 points close to the body-car
sweeping all to get a fender that have sections with G2 continuity
at the end of the video you can see i did a close-up showing a perfect junction (G2-based)

M

yep, I understand you.

This is how it looks in precise terms.

I think simple man never distinguish G1 from G2 or G3.

Hi Andrei,

>All I get from my experience is that G-0 (circular fillet) is look very digital...

Circular fillets are G1 continuity or they should be. G0 is basically when two curves or surfaces just touch each other with no continuity.

Here's a video explaining it simply http://cadjunkie.com/1113/continuity-101

Cheers

Danny T,

I name G-0 just arbitrarily, in MOI its name is - Circular. So it looks like my mistake..

But it's the only mistake I made.

Hi Andrei,

>But it's the only mistake I made.

Well....everything you show after G1 is incorrect G2 and G3 are curvature continuous and are useless when used with straight curves or planar surfaces.
The video I posted above explains it very well.

Cheers

Danny T,
No)

all I made I made with MOI Fillet function.

Fillet:

MY | in MOI
-------------
G0 | Circular
G1 | G1
G2 | G2
G3 | G3

Try it your self, and you will get the same result as mine.

I changed G0 to Circular.

All other continuity was taken from MOI filet function like in first screen.






Download project and try it your self:
https://docs.google.com/file/d/0B1uI4ljG15POdTE1bjFxTXNackk/edit?usp=sharing

If you show points on surface that was made by blend you will se the same points.

Circular - 3 Points
G1- 4 Points
G2 -6 Points
G3 -8 Points

G1- 4 Points
G2 -6 Points

@Andrei:I think simple man never distinguish G1 from G2 or G3.
I understand what you mean ;) but is not always correct

G2 means to have a continuity of the curvature when join two curved surfaces together
It's obvious that is useless if your surfaces are flat,like Danny correctely says
But it can be useful for you because it give you a real smooth junction and speed up your workflow
I know that your target is rendering so: is it better to have a clean surface made from a G2 blend,quickly?
I suggest you to consider this option when you model and when possible,it will give you better results :)

Consider this like a kind suggestion without misunderstandings..you got this option..use it ! :)

M-Dynamics,
Previously I tried to use G2 every time to get smoother result. But in organic shapes it starts to produce kinked results. So I stop to lose time trying G2 and start to use G1 everytime :)
I now this workflow is not good for everybody, so you can do it as you like )

Michael spent alot of time to adjust and get the nsided tool he wanted. He mentioned that "for now", in it's initial release, it is only doing G1.. Later he will be working to get the curvatures in to it...

I think you were asking this?

Hi Pilou,

> Does 3 a maximum?
> And that works also with 3 on a side and 2 on the other side ?

There is no specific maximum, yes it can work with 3 on one side and 2 on the other side.
