# Unmark seam

Selected edges or the outlines of a polygon selection can be removed from an existing *Seam Selection*. *Seams* are evaluated by certain UV functions and then interpreted as cuts or openings in the UV unwrap. This allows you to define specific UV islands and place cuts through the geometry to calculate a flat UV unwrap.\
The same command is also available directly from a *Seam Selection Tag*.
