assigning different pipe diameters to different curves

If you have a list of 37 curves as an input to the Pipe Component then all you need is a list of 37 values to get a different diameter for each. You will only need to use the graft function if one of your data inputs is a data tree structure. The graft will convert a single branch of 37 items into 37 branches of single items

 

EDIT: you don't actually need the same number of values in each because grasshopper will employ the data matching rules, depending on which is selected for that component. Longest list will apply every value in the short list with the corresponding value in the long list and then apply the last short list value to the remainder of the long list. Short List will match only the Short list values with their corresponding long list item and then ignore the remainder. Cross reference will do every item in list A with every item in list B. (Similar to having one list grafted and the other not)

Thank you very much for your quick reply.

 

Three different diameters more or less distributed RANDOMLY to different curves.

 

I have attached a little network of curves as an example file and the grasshopper file I know is wrong--

So the grasshopper file would be something like only: Crv(curve)> Pipe but with the radius of the pipe with a list of three radii?

 

how does it pick the curves randomly to apply the different radii??

 

Thank you so much in advance. Really appreciate it.

 

Best,

Anni

From a domain of 0 to 2 (3 options) you can randomly generate just the integers (I = true) with this list you can weave a list of values into your pipe radii input

Hey Danny,

the weave comnponent is a cool idea. I have to integrate this component more into my thoughts. This is the way I do this normally.

Best Regards
