Hi Brian
I think I managed to do this like yours. Please I would appreciate your comment.

Hi @marcel1,

Yes, thatā€™s pretty much the same, nice job! You used face boundaries for the multipipe lines instead of mesh edges but it works. Hereā€™s what I did in case you didnā€™t see it on the Instagram link.

This workflow gets even cooler when you start leveraging the size points input on the multipipe component. Check out How can i control node diameter at specific points with multipipe? - #3 by nik.mvk

One tiny tweak - you can even just connect a mesh directly to the MultiPipe input and it will automatically use the mesh edges (or ngon boundaries if itā€™s the dual) to build the pipes around:

@DanielPiker Awesome! Thanks for pointing that out :slight_smile:

Hi Brian, thanks for the feedback. I am quite efficient with Rhino. (Iā€™ve had Rhino 5, 6 and now 7. I am self learning GH which I find to be outstanding but boy! itā€™s sometimes hard to understand the meaning of the elements, ie ā€œevaluate Srfā€ or ā€œdomainā€ ā€¦etcā€¦ but I am getting thereā€¦This forum is extremely helpful. Thanks again.

Weā€™ve done Rodin and now Koons! Itā€™s almost too easy isnā€™t it :slight_smile:

Hi brian
i also thought of my seat right away.
looks clean. much easier and faster than my way. I have slightly different sizes of the holes in certain areas. but that is also possible, I think.
regards
nik

Yes, your seat had that extra variable making the GH file more complex but using size points too is really interesting design wise. I hope your project turned out well.

ā€œFigura recostadaā€ (Quads)
( yes, easy to do in digital format,
but ā€¦ ā€˜Materializingā€™ the Sculpture can be even more cumbersome, of course).
Anyway interesting to see the formal study
under another optical-digitized.

are you going to do a video walkthrough of this for people that have never opened up grasshopper before??

15

Sure I can do thatā€¦ there are two bits really, TriRemeshing something and then making the SubD MultiPipe from that. Itā€™s an easy one to get into Grasshopper with.

In itā€™s simplest form it can be as easy as this:

Just find the wireframe
and multiple pipes.
(Using Quads for modeling, ā€¦ Just change the SubD to Nurbs).

Many years Drawing by hand, ā€¦
now with Rhino everything is very simplified.

Hi @zale_orcid ā€¦ I posted this video which covers using MultiPipe in GH too, hope it helps!

19

Are those lines SubD friendly? ā€¦
I get another result when doing the Multipipeā€“does not softenā€“
ā€¦I donā€™t see ā€œCapsā€ in Multipipe GH either.
Will there be a new version of that GH command?!
Thanks

Hi @claudiofeldman

If you update to the latest service release you should see the Caps option in the GH component.
About your image above - I canā€™t say for sure without the file, but I suspect your issue is either:
-The curves are not split at the grid intersections so each long line is getting treated separately
or
-They are split, but there are gaps between the end points bigger than the tolerance.
