Rhino, Grasshopper Multipipe

Hello all, I have a question.
Currently, I’m using Rhino 7 and Grasshopper. After using Loft with three curves of different sizes and shape, and working on it, I used Multipipe. However, the pipes are not connecting smoothly along the guideline from the Loft, and they appear to be disconnected. I have a file and photo.
Can yo help me?

please internalize the Geometries and repost the file (a guide on how to do that can be found on first thread of this forum, at point 3)

As @inno says, please internalise the data so we can see the curves.

My guess is that the gap where the structure is not joining up is where there’s a seam on your initial surface that you have panelled or processed somehow to create the woven lattice.

You probably have to manipulate your data structure somehow so the end of the list joins up with the start. A bit like when you use shift list and select “Wrap”

Hello!
I’ll go ahead and upload the modified Grasshopper file and the Rhino file

The problem is because the surface morph is not wrapping the hex cells perfectly around the surfaces. It leaves what looks to be a half cell gap…

I’m not sure how to fix this and it might still leave a gap.

It’s all about how the line network wraps around the surface and joins back to itself.

I reckon someone on here can solve this, but it’s not me :slight_smile:

So I can do this with meshes instead of surfaces…

Use TriRemesh to mesh the surface and use the Dual Mesh output, which is hexagons. (and maybe the odd pentagon)

Use the Target Length parameter to change the size of the hexagons. You don’t have control of the size in U and V directions but TriReMesh is great for keeping them nice and even.

Had to change a few components downstream to use PointOnMesh instead of PointOnSurface etc.

Used MeshFaceBoundaries to give the equivalent of the HexGrid Cells.

I’ve just done it for one surface so if you like this method you can try and adapt the other surface the same way.

Thank you so much for your help; it was exactly the feeling I wanted!! Thanks to you, I was able to solve this problem, so once again, thank you!
