Generative design won't pass through this node

I have a GD script where all the outputs were * (not working)

I put in some test outputs and traced the error to the node “Group Parallel Lines” from GeniusLoci package.

I copied the Python from there just to see if there were any obvious errors. There weren’t and the outputs were still *

If I put a Data.Remember node it then my GD works.

Question is … What’s in the Python that it’s not liking?

My guess is one of the lines I’ve drawn a green line next to.
Can anyone shed light on this please?

It was annoying me so I re-wrote it just to with no external references at all and now the GD is happy :slight_smile:

Yup. You had Revit references before, which have to be cached for GD. Even if the node isn’t using Revit or Revit data the reference still causes trouble.

Was it the lines I’d marked?

Yes. Even loading the RevitAPI and RevitNodes references will cause issues.
