+Extrusion Fuse
+=============
+Extrusion Fuse feature extrudes selected objects along their normals or the selected axis and fuses the result with other objects.
+
+To perform Extrusion Fuse in the active part:
+
+#. select in the Main Menu *Features - > Extrusion Fuse* item or
+#. click **Extrusion Fuse** button in the toolbar

+- **Base objects** - contains a list of objects selected in the Object Browser or in the Viewer, which will be extruded.
+- **Axis** - if selected, it will be the direction of extrusion, otherwise objects normals will be used.
+- **To size** - size for extrusion in the direction.
+- **From size** - size for extrusion in the opposite direction.
+- **Fuse with** - contains a list of objects which will be fused with the result of extrusion.
