ElementTransformUtils.MirrorElements

Description:
Mirrors a set of elements about a given plane.

Remarks:
Optionally, copies of the elements can be created prior to the operation and mirroring is then performed on the copies instead of the original elements.

Autodesk.Revit.DB.Document

document

The document that owns the elements.
System.Collections.Generic.ICollection<ElementId>

elementsToMirror

The set of elements to mirror.
Autodesk.Revit.DB.Plane

plane

The mirror plane.
System.Boolean

mirrorCopies

True if mirroring should be performed on copies of the elements, leaving the original elements intact. False if no copies should be created and the elements should be mirrored directly.

Return Value IList<ElementId> A collection of ids of newly created elements - mirrored copies. It is empty if the mirrorCopies arguments is false.

Autodesk.Revit.Exceptions.ArgumentException

elementsToMirror cannot be mirrored. -or- The given element id set is empty. -or- One or more elements in elementsToMirror do not exist in the document.
Autodesk.Revit.Exceptions.ArgumentNullException

A non-optional argument was NULL
Autodesk.Revit.Exceptions.InvalidOperationException

Thrown when the elements cannot be moved (e.g. due to some of the elements being pinned).
