Hi Jesper. I've posted a script here http://www.grasshopper3d.com/profiles/blogs/tapeworm-a-script-for-creating that may work for this. /Mårten

Thanks a mill, Daniel - it works now!
I also, wanted to complement new Kangaroo's improved interface and readability. Great job and thank you again!

Looks like you you don't have the latest Kangaroo (0.044), which you can get from the kangaroophysics site

Daniel,
Thanks for your reply, but, I have trouble opening your .ghx file. I have all the latest Rhino, GH and Kangaroo, but I keep getting an error message (attached). What could be wrong?
Daniel Piker replied to Jesper Thøger Christensen's discussion 'paper strip model with kangeroo?' in the group Kangaroo
Here's a closed loop of 'paper' in Kangaroo. It has 2 anchored segments which you can move and twist about to change surface.

Jesper or Marten,
I am trying to model a very similar thing, but just can't get it right. Could you please send me the definition you came up with?
Thanks!

Hey Chris
I posted the question here as…
Jesper Thøger Christensen replied to Jesper Thøger Christensen's discussion 'paper strip model with kangeroo?' in the group Kangaroo
Yes exactly Mårten, could you maybe post or send the files?
of course the ends have to join up but its pretty close.
But how did you determine the rulings? just by trail and error?
And what if the transition would not be liniar? Because as you…

Something like that?

hey jesper,
it seems like you didn't attach any images. send them over and i can have a look at it. greetings to switzerland.
best

if I just loft the lines in each fold you still dont get a perfectly straight strip as you can see in the image below.

Yes okay i get that the rulings should not be perpendicular to the edge, but i still dont get how you will do it from the quad example
Can you maybe make it in rhino and post it as before?
And for the example with the elipses how did you then find…
Jesper Thøger Christensen replied to Jesper Thøger Christensen's discussion 'paper strip model with kangeroo?' in the group Kangaroo
but how is this different from the the lines of the quads you suggested?
When i try to make the ruling from the lines of your guads i get the same deviation
Is it not just a matter of how close the lines are to each other?
Mårten Nettelbladt replied to Jesper Thøger Christensen's discussion 'paper strip model with kangeroo?' in the group Kangaroo
Careful when picking what lines to loft! The straight lines in the surface on the right are not aligned correctly with the ruling lines of your single-curved surface. Which means: it will be slightly double-curved.
It will still unroll to a straight…
Jesper Thøger Christensen replied to Jesper Thøger Christensen's discussion 'paper strip model with kangeroo?' in the group Kangaroo
Actually i tried to make a lofted surface from the centerline of each triangle and i turns out to be a straight strip when i unroll it in rhino so thats great then i just need to adjust the angles to make up the desired strip than closes up on…
Jesper Thøger Christensen replied to Jesper Thøger Christensen's discussion 'paper strip model with kangeroo?' in the group Kangaroo
Actually I already started on it about 1 hour ago, so just before you sent the last reply.
A coincidece that we thought of using the same technique
However i tried with triangles in this first step but i will try with quads as well.
Thank you

how to make a digital model of a twisted cylinder
I'm currenty doing a study project where I bend/twist a cylinder. see images below
Anyone who have an idea how to construct this geometry.
Its simply a cylinder where you grab two opposite sides and rotate one of the sides to the desired angle.
In the images this is approximately 270 degrees
