This tool is used to replace all objects in the scene that have similar geometry (for example, all screws of the same size in a machine) with a single prefab, based on one of the selected shapes.
The feature can be found under Utilities > Mesh Tools > Mesh Replacer.

Whether or not an extra filter should be applied to the objects using mesh area comparison.
Mesh Area Parent: The parent object under which the mesh area comparison must be done.
If selected, use the circumference of a plane on the mesh (an area where connected triangles have a similar normal) as a comparison to check if objects share this plane, as an extra similarity check.
Keep Local Rotation
If selected, ensures that the local rotations of the prefab instances are the same as the object that they replace.
