Hi US, are you referring to the List option in the input parameters of scripting components?
If so, then list will change the way the parameter feeds data into the component. Most parameters in Grasshopper are not lists, because the components operate on a single data item at a time. However, sometimes you need lists because multiple inputs have to be combined to create a single output (such as Lofting, where multiple input curves become a single surface; or Polyline, where any number of points are used to create a single curve). If you enable the List option on inputs, it will change the signature of the Script function, and it will treat all the data inside that parameter as a single blob (i.e. it will not iterate over the data). -- David Rutten Robert McNeel & Associates On Nov 14, 12:42 pm, "[EMAIL PROTECTED]" <[EMAIL PROTECTED]> wrote: > what does this list do beyond holding any streams flowing into it? > does it interact with the scripting components in a special way? > > jonathon
