We can access, add, and edit these parameters through the Revit API, so let's have a look at how we can get parameters from an element, but first what actually are parameters? Parameters come in the form of parameter objects, each object can be retrieved and set from an element using the API, as we can with the user interface. Each parameter object has a definition object associated with it, which describes the parameter name and the type of parameter it is.
