Data stored in grasshopper components is typically accessed by referencing a list index (e.g. 0 for the first item in a list, 1 for the second and so on) as objects don't have names. The Send Meshes component in Fologram allows you to attach a name to each object in order to easily recognize it later. For instance, you could check to see whether a user had clicked an object with a specific name, and then do something if they did.
To demonstrate how this filter works,the definition shown above creates two lists of data - one containing geometry, and one containing matching names. E.g. the first geometry has the first name, second geometry has the second name etc. A Member Index component is then used on the list of (unique) names to output the list index of the matching name, if it exists. This index can then be used with the List Item component to select the matching piece of geometry.
