Generative Design Error: Output No Value

Following Jacob’s suggestions:

  • List item I opened the script in Dynamo Sandbox. After installing all required packages, it works. Only two nodes related to Revit elements are not working, since in the sandbox, there is no direct connection to Revit’s element.

  • List item All packages in the dependencies folder are there, so they should be uploaded to the GD study correctly.

I am not an expert in Dynamo, so perhaps I am doing something wrong and I have no idea where to find the root of the problem…

I would really appreciate your help.

BR,
