Hi,

I can’t read you’re nodes.
Please zoom in and use “Export Workspace as Image”

The good workflow is to divide cutting openings by two stages:

  1. Generate opening family instances.
  2. Cut openings

this error is typically caused by null values in the list. clean it with a bool mask or a node. I have found the nodes to be unreliable, i just use a bool mask.

Thank you for your response, I am new to Dynamo. Do you mind showing me what you mean?
