How do I add study types in Refinery?

How do I add my own study in Refinery version 0.62.2?

This is necessary to make a study for Parking Layout (see attached screencast) ?

  • Export for Generative Design fails
  • Create study
    • You can only choose 3 samples studies.
    • How do I add study types ? -> didn’t work

Thanks in advance.

You need to clean up your output nodes so the graph exports. Do this by modifying your graph to ensure the following:

  1. All outputs are single items, not lists.
  2. All outputs are numbers (doubles or integers).
  3. All outputs return a value, not a null when run.

You should then be able to use the graph as a study type.


I don’t quite understand what you mean.
The Dynamo file have been added. Can you possibly indicate an example where things go wrong?

Thanks in advance.
