Revit vs Dynamo API

Hi @Daniel_Woodcock1 ,

Thank you for the reply.
What I meant by Dynamo API are the properties and methods of the objects used inside the Dynamo Python node.

For example, ‘CutainPanel’ object inside Dynamo Python node has a property ‘Boundaries’, while its Revit counterpart ‘Panel’ object, has no such property.
Where can I find the Dynamo documentation on ‘Boundaries’ property?
