Lock Parameter

Lock Parameter – Excluding Elements from Execution

The Lock Parameter lets you exclude individual elements from rule execution without modifying the rule itself or manually adjusting the selection.

How the Lock Parameter works

In Settings, you choose any Yes/No parameter from the current Revit project as the Lock Parameter. If an element has this parameter set to Yes, the MultiPushTool skips it during execution — no parameter value is written to that element.

Logic

Lock Parameter value on element	Behavior during execution
Yes (1)	Element is skipped — no parameter is written
No (0)	Element is processed normally
Parameter not present on element	Element is processed normally (no lock = not locked)

Setting up the Lock Parameter

→ Main window: Menu (gear icon) → Settings → "General" section

A new "Lock Parameter" dropdown appears under General. It lists all Yes/No parameters in the current project.

Open Settings via the gear icon.
Select the desired parameter from the "Lock Parameter" dropdown.
Confirm with OK.
Elements with this parameter set to Yes are skipped on every execution from now on.

To disable, select the first empty entry in the dropdown.

Important: The Lock Parameter applies globally to all rules. It cannot be enabled or disabled per individual rule.

Which parameters appear in the list?

Only Yes/No parameters (YesNo type) existing as project or shared parameters, sorted alphabetically. Built-in Revit Yes/No parameters and family-only parameters are not shown.

Typical use cases

Scenario	Parameter example
Mark elements as "checked/done" and exclude from further batch changes	`MPT_Locked`, `Checked`
Protect elements being edited by other disciplines	`Do_Not_Edit`
Define exceptions within a large rule set	`MPT_Exception`

Tip: Create a project-specific shared parameter (e.g. MPT_Locked) bound to all relevant categories. This lets you lock and unlock individual elements directly from within the tool.

Execution log behavior

Skipped (locked) elements are not listed separately in the log — they are excluded from the count. The "Y parameters set (of Z)" figure reflects only elements actually processed.
