+Face Set Boundaries Node
+************************

+   :align: right
+   :alt: Face Set Boundaries node.
+
+The *Face Set Boundaries Node* finds the edges which lie on the boundaries of 
+specified regions. These edges could be used to mark seams for UV unwrapping, 
+for example.
+
+
+Inputs
+======
+
+Face Set
+   Identifier for which group of faces this face belongs to. All contiguous faces
+   with the same value are in the same region.
+
+Properties
+==========
+
+This node has no properties.
+
+
+Output
+======
+
+Boundary Edges
+   Selection of the boundary edges of the different face sets. An edge is
+   considered to be at the boundary if it lies on at least two faces with
+   different identifiers.
+
+
+Examples
+========
+
+.. figure:: /images/modeling_geometry-nodes_face-set-boundaries_voronoi-seams.png
+
+Combined with the :doc:`UV Unwrap Node </modeling/geometry_nodes/uv/uv_unwrap>`,
+this node is used to turn the face sets (right cube) into a UV map for a texture (left cube).
