Multipipe not working as should?

I am working on some complex multipipe structures, very powerful… when it works. Can someone have a look at this small script, I am trying to understand why the first image is not working yet when I snap it to the end as in picture 2 it seems to work?

Now sure why this is happening, appreciate any help

In image 3 the desired result however why does this only work when the curves are individual?

Hi @w1743763
The Curves input is List access type.
So if a data tree is input here, it will make a separate result for each branch.
If you right-click an input you can choose the ‘Flatten’ option to turn your tree into a list so the curves are all processed together.

Hi -

I see that error here too when running Rhino 7.4. I don’t know in which version this was fixed - you might try changing your update frequency to “Release Candidates” to install the current public 7.5 build.

You might want to divide and shatter your input curves to get better definition.

@DanielPiker it would be nice to be able to choose the number of around segments. (13.5 KB)

Thanks can you advise a bit more on how to do this?

Hi Martin I have tried to explode the curves and didnt work either


Hi -

Go to Rhino Options > Updates and Statistics > Update frequency and set it to Service Release Candidate.
