Before a parameter can be used in a RebarShapeDefinition, it must exist in the definition’s document. There are two ways to achieve this. It can be bound to one or more categories in the document using the Document.ParameterBindings property, or it can be created by calling RebarShapeParameters.GetOrCreateElementIdForExternalDefinition().
