Hi Anis, also if your curves do not meet each other smoothly at the pole area where they touch, that not help make things smooth. It looks like you have some end tangents of the curves not aligned to each other like this:






You want to have curves meet up in a shared tangent, which means having the end and first inside control points of each curve all on the same line.

Otherwise it means your curves are already starting out not smooth to one another.

Hi Anis, so here's an example of how you could get a better surface from your particular curve layout.

I aligned the control points at the tip and also note that I added a circle in there which tends to help to even out the shaping of the tip to make it more proportioned to a dome as it comes together to the pole.

Also note that you should select all the curves and make 1 single big network for the whole thing instead of doing it in separate pieces.


But if you make it by modifying surface control points of a surface of revolution (as in lyes example), that will tend to give the best smooth quality.

Hi Michael...

>> It looks like you have some end tangents of the curves not aligned to each other
a ha..., I am not aware about that...

I dont want use freeform technique that Iyes show on his tutorial.
I will stay to use curve strategy.

Regarding Network, is it possible to move the seam edge, because it will interfere when I use Blend like Iyes tutorial ?

Seems videos Lyes Helmet are not yet working ? :(

Just be aware that there are some potential difficulties with the strategy you have chosen then...


> Regarding Network, is it possible to move the seam edge,

It will end up reflecting the seams in the closed curves that are used as inputs into the network.

Try rotating the circle by 90 degrees around its own center point, that should then put the seam in a better place for you.

Yes, I am aware. But it give me challenge and push me to find best idea and best construction geometry.
Curve strategy is more "mechanical way" for me and more accurate.

>>Try rotating the circle by 90 degrees
Yes it work...

Thanks

Michael,

"One key thing is probably to not worry about the face cutout area at first, instead focus first on making a full dome shape and then trim or boolean out the face area rather than trying to incorporate that outline into the initial surfacing."

In this kind of model that's again so very true, haha, before you said this and I looked at the helmet I was already thinking "pffff, ok so i would lay a patch there, and there and then intersect and trim..."
I'm using Solidworks today but come from a poly background, and let me tell you, it never truly goes away! ;)
