Loft between Polylines Error


Following the Optimizing Grasshopper Definitions Explained! document, I downloaded the suggested example.

However, attempting to run the definition, produces the errors illustrated on the uploaded pictures below.

Any insights would be greatly appreciated.

Thank you in advance,

You need to update your Rhino. The version you are using is a version before “RebuildNormals” existed in Rhinocommon, that is why it is telling you it doesn’t exist.

Thank you Michael.

I would like to suggest to the ShapeDiver team, that any possible Rhino and GH version requirements to be added to the documentation and the component.

Best regards,


Thank you for the support @Michael_Pryor.

I agree that the documentation and the model should include a note about the minimum Rhino version it is compatible with. We will update it accordingly.

Thank you Mathieu :slight_smile:

Just keep in mind anytime you get a message that something couldn’t be found it is a good sign that it’s time to update. It could also mean that the method is misspelled or you are missing an assembly reference. In this case it is a version thing.
