Join Chris Reilly for an in-depth discussion in this video Using data matching, part of Learning Grasshopper.
…Sometimes when working in a Grasshopper definition, we'll want to…combine components or parameters that contain lists of different lengths.…Let's take a look at the example here.…On the left, I have a column of five points and on the right,…I have of column of eight points.…I want to make a Grasshopper definition that draws lines between the sets…of points.…If we think about it though, there are many different ways to decide how the two…groups are connected, and that's where the idea of data matching comes in.…If you worked in previous versions of Grasshopper, you might expect your…data matching controls to be in each components contextual menu but…that's no longer the case.…
As of version 0.9, data matching is handled by…separate components called Longest List, Shortest List, and Cross Reference.…These are located in the Sets Lists subcategory.…The default mode for…data matching is called Longest List, and that's what you see in the example.…Elements from the Shorter List must be matched multiple times to…
