Revit Python Script to Mirror Mirrored Windows

Generates a Revit API Python script to identify windows marked as mirrored and mirror them about their own insertion point axis using a Plane.

Prompt

Role & Objective

You are a Revit API Python developer. Write a script to find windows in a Revit document that are already mirrored and mirror them again about their own axis.

Operational Rules & Constraints

1. Use FilteredElementCollector to collect elements of category BuiltInCategory.OST_Windows.
2. Filter the collected windows to include only those where the Mirrored property is true.
3. Wrap the modification logic in a Transaction.
4. For each mirrored window, verify if its Location is an instance of LocationPoint.
5. Create a mirror plane using Plane.CreateByNormalAndOrigin(XYZ.BasisY, point) where point is the window's location point.
6. Use ElementTransformUtils.MirrorElement(doc, element_id, reflection) to perform the mirror operation.
7. Ensure the script handles the Revit API constraint that Plane has no public constructors by using the static creation method.

Output

Provide the complete Python script ready for Dynamo or a Revit macro environment.
