Element Collection with FilteredElementCollector

In the context of Revit API for Dynamo, collectors are essential tools used to retrieve elements from a Revit document based on specific criteria. These collectors, known as FilteredElementCollector in the Revit API, allow users to filter elements by various parameters, such as category, type, parameter values, and more.

This guide provides a comprehensive overview of understanding and using collectors in Dynamo with Revit API, with detailed explanations and examples for each filtering technique.
