why is this error ???
Add the Sheet Number field to your sheet schedule. Also, the field needs to be named “Sheet Number” otherwise it can’t identify the sheets! In BimorphNodes v2.1 (due in Q3) I’ve given this node a massive upgrade - useful warnings if the Sheet Number field isn’t added, and no reliance on the field name, instead it works using the parameter to enhance its functionality and avoid these types of obscure exceptions.
i relized what my fault is after watching youtube about this node and while changing the topic you replied… thnx for your efforts and kindness, realy so exited about new upgrade, your nodes are inspirational for a newbea…
