# Clean Up

The **Clean Up** operator is a legacy function back from the days when the random operators often ended up with messy topology.

It is used to get rid of zero area faces, double faces or faces that have the same area occupying the same space and vertices that are on a straight edge with no other connections.

This is kept as the functionality it provides while no longer a common use case scenario is still useable when the situation needs it.
