Project parameters (parametri_progetto)

What it does

Lists all the project parameters of the model, shared or not (not global parameters, not family parameters), like the "Parameter manager" (Gestione parametri) window. For each parameter:

id, name and, if shared, GUID;
binding (instance or type), data type and "Group parameter under" group;
the categories it is bound to;
how many elements have the parameter and how many have a value, counted in the whole model without linked models (for type parameters, types are counted);
the resulting use: All filled, Partly filled, Empty, No elements (or Not counted).

A value counts when it is really there: a non-blank text, a reference to a valid element; numbers and yes/no count once set, even when they are 0.

At the top of the list are the model's totals: how many project parameters, how many shared, empty, partly filled, all filled and not counted, and how many pass the filters.

How it works

Your AI asks for the list, with the filters it needs (for example only the empty parameters, only shared ones, only those of one category).
BIMit reads the project parameters and, unless asked not to count, reads each category once and counts the values on all its elements.
Your AI summarizes the result for you or uses it in the next steps, for example to suggest which parameters to delete.

Example requests

"Which project parameters are empty across the whole model?"
"List the shared parameters bound to Rooms, with how many rooms have them filled in."
"How many project parameters does this model have, and how many are type parameters?"

What changes and how to undo

Nothing: the tool only reads. The model and files do not change.

Limits

Works on a project, not on a family open in the Family Editor.
In large models counting the values can take time: with conta set to false the list comes back at once, but without counts, and the uso filters that depend on the counts find nothing.
Linked models are not counted.

Parameters

Parameter	Meaning
`cerca`	Words to look for in name, parameter type, instance/type, data type, group, categories and use (all must be present).
`tipo`	`condivisi` (shared, with GUID) or `di_progetto` (project, not shared).
`legame`	`istanza` (instance) or `tipo` (type).
`uso`	`vuoti` (counted and without values, also with no elements), `con_valori` (at least one value), `non_contati` (not counted), or an exact use: `nessun_elemento` (no elements), `in_parte` (partly filled), `tutti_compilati` (all filled).
`categorie`	Only parameters bound to at least one of these categories (OST name, name in Revit's language, or id).
`conta`	Count the values in the elements (default `true`; `false` is faster).
