Hi Everyone,
I am going from selecting a family from a UI++ dropdown to a FamilyInstance.ByPointand Level node. The warning I am getting is telling me that my input is a Revit.Elements.FamilyType , but the node input wants a Revit.Elements.FamilyType (no bracket pair ) connection. Is there a way to change the …FamilyType? I will post a dynamo network tomorrow, if that will help.
Thanks in advance!
The bracket [] indicates you have a list of family types, not a single instance.
List.FirstItem will pull the first item out of the list, so if you only have one thing in it you’ll be good to go; but if you have many, you’ll need to look into list lacing and list levels…
Hi Jacob,
First, thank you for your help.
I extracted the relevant nodes from my network to test this and it works (posted image).
But when I return to my full node network and insert & connect a List.FirstItem or List.Flatten node, the familyType warning returns.
I am now researching list lacing and list levels.
Your image is illegible. Make sure the node names are visible before taking a screenshot and be sure to pin all your node preview bubbles.
Check the list structure of the output list first and then determine what’s necessary to reduce to a single item. You may need a Flatten and a FirstItem since Flatten still returns a list. You could also just use @L1 list level to force each family type in the list to be placed.
Flatten did the trick. I turns out I that the user input for level in the full node network was the culprit. Resolving that is for another topic.
Thank you, NIck_Boyts
