Dictionary Nodes

Dynamo 2.0 exposes a variety of Dictionary nodes for our use. This includes create, action, and query nodes.


  • Dictionary.ByKeysValues will create a dictionary with the supplied values and keys. (The number of entries will be whatever the shortest list input is)
  • Dictionary.Components will produce the components of the input dictionary. (This is the reverse of the create node.)
  • Dictionary.RemoveKeys will produce a new dictionary object with the input keys removed.
  • Dictionary.SetValueAtKeys will produce a new dictionary based on the input keys and the values to replace the current value at the corresponding keys.
  • Dictionary.ValueAtKey will return the value at the input key.
  • Dictionary.Count will tell you how many key value pairs are in the dictionary.
  • Dictionary.Keys will return what keys are currently stored in the dictionary.
  • Dictionary.Values will return what values are currently stored in the dictionary.
Overall relating data with dictionaries is a magnificent alternative to the old method of working with indices and lists.
