Seems you can make that only inside Moi ;)
hum hum not so evident I have some seams and my circle is not enough big :D

Thank you Pilou!

It works great to divide the surface in 8 parts and sweep them separately. Didn't even think of that, I'm always afraid that there will be kinks between individual surfaces where they meet. But the way you've dividend it there's no risk for that. It would take some effort to adjust the curves so that the parts will meet in a nice way when you copy the whole thing.

Thanks again for showing me!

what's how Erwin Hauer is doing it...

Hi Lars,

I would build that interlinking surface slightly differently.

This is just a very quick example (took about 3 minutes to build)

Create a curve which I then rotated(copied) 90 degrees and mirrored.



One rail sweep to create surface. Then booleaned out 4 circles.



Shelled the surface.



Then made arrays.

Yannada - thanks for the link, I will sure check it out. Was inspired by Rinus Roelofs - http://www.rinusroelofs.nl/pr-c-holes/pr-c-holes-00.html

Manz - another possibility that I would've never thought of. I'll give it a try.

/Lars

This was a nice experiment, I'll go on to try out the different suggestions you've given me, just a quick sketch of another one, not so smooth yet...

/Lars

@Manz: Damned! That is "the solution" the more easy ! Bravo ! :D
I am so dumb to not have though to that :)

Very cool links!

I decided to build that surface from a network (egg carton)



Create the surface.



boolean the holes, then copy and postion.



Add shell




There are some nice shapes shown on the link, I will have to play more.

Really nice, but now you have to relate how you go about in creating an egg carton surface.

/Lars

Create a curve, here I have used the "through points" curve to create a wavy curve using snaps.



Use that curve and create the square boundary, then select all 4 curve and select "network".



I have attached the curves which may better explain.

Maybe this link can interest you ;)

Some amazing things anywhere in this site!

Hi Pilou,

I will have to make time to take a longer look at those images,.. some strange shapes indeed.

Thanks for the link.

Hi Lars,

I had a play with building the 3 surfaces interlocking. It did not come out exactly as planned, but was OK.

Hi Manz,

nice one. It's a nice interwoven structure and I plan to experiment more with it too.

Tell me, the red color... remember seeing a screenshot from Michael some time ago where he showed an idea for that, but is it actually implemented in the latest beta? How does it work?

I'm trying to learn a bit in the parametric plugin for Rhino called Grasshopper. So after all the tips and ideas from you, Pilou and Yannada I figured I had enough understanding of this surface to try it out in Grasshopper. So now I can change at least a few parameters with sliders in Grasshopper.

I have not seen anything in the latest beta for changing colors of an object, I would think that will be included when the Groups are added.

On the screengrab, I just have (on that setup) the surface selected color set to red in the MoI ini file. The entry I changed was "SurfaceSelectedColor=" and made it 255.0.0

hello all :)

very interesting Lars ;)

cool site about Erwin Hauer !

Wow! Very beautiful.

I've only just started to imagine those intersections on a 3d-surface, and thought I would start easy with a cylinder or something...

Now I know what to head for! Excellent.

Hi Lars,

>>I've only just started to imagine those intersections on a 3d-surface, and thought I would start easy with a cylinder or something...

With the current MoI toolset you will struggle and have to make a lot of construction for the interweaving surfaces around a cylinder (or sphere etc).
For solid work I now usually use VC pro which gives more advanced filleting/shelling etc. The 2 interweaving surfaces I made (image posted earlier in the thread) I imported them into VC pro and bent them around a circle.

Hi Manz, and thank you for the warning..

Actually this was all meant like an exercise in Rhino - Grasshopper. I've made a definition that lets me control some parameters.

The idea is to go on and "map" this geometry to a surface in Grasshopper. But I haven't got round to that yet. On Torolf's site he mentions Paracloud, and I thought I'd try it out in Paracloud Gem too, basically you open up this interwoven figure and some interesting surface and then let Gem map the figure all over the surface. But I'm still at the part where I'm trying out different variations on this theme.
